1. #1Early Child

   Keys: baby, infant, little boy, little girl, 1 year old, 2 years old, 3 years old, 4 years old, 5 years old, 6 years old,

   Early childhood typically ranges from infancy to the age of 6 years old. During this period, development is significant, as many of life's milestones happen during this time period such as first words, learning to crawl, and learning to walk.

2. #2Sensory Motor Stage

   Keys: infant, baby,

   Infants have the following basic senses: vision, hearing, and motor skills. In this stage, knowledge of the world is limited but is constantly developing due to the child's experiences and interactions. When an infant reaches about 7–9 months of age they begin to develop what he called object permanence, meaning the child now has the ability to understand that objects keep existing even when they cannot be seen. An example of this would be hiding the child's favorite toy under a blanket, and although the child cannot physically see it they still know to look under the blanket.

3. #3Preoperational Stage

   Keys: toddler, 2 years old,

   During this stage, young children begin analyzing their environment using mental symbols, including words and images; the child will begin to apply these in their everyday lives as they come across different objects, events, and situations. Children at this point are not able to apply specific cognitive operations, such as mental math. In addition to symbolism, children start to engage in pretend play, pretending to be people they are not, for example teachers or superheroes; they sometimes use different props to make this pretend play more real. Some weaknesses in this stage are that children who are about 3–4 years old often display what is called egocentrism, meaning the child is not able to see someone else's point of view, and they feel as if every other person is experiencing the same events and feelings that they are. However, at about 7, thought processes of children are no longer egocentric and are more intuitive, meaning they now think about the way something looks, though they do not yet use rational thinking.

4. #4Concrete Stage

   Keys: Child, kid, 7 years old, 8 years old, 9 years old, 10 years old, 11 years old

   In this stage, children between the age of 7 and 11 use appropriate logic to develop cognitive operations and begin applying this new way of thinking to different events they encounter. Children in this stage incorporate inductive reasoning, which involves drawing conclusions from other observations in order to make a generalization. Unlike in the preoperational stage, children can now change and rearrange mental images and symbols to form a logical thought, an example of this is "reversibility," where the child now knows to reverse an action by doing the opposite.

5. #5Infancy Stage

   Infants-Toddlers 0-2 years old

   Girl Vagina: The Labia Majora can spread to the sides by about an inch. Labia Minora is behind Labia Majora and obscured, young, pale, and underdeveloped, an arched ridge above the vaginal opening. The clitoris is obscured by the clitoral hood, which is about the size of a grain of rice. The vaginal opening has a thin hymen film covering it which is no larger than a bean. Inside the vaginal canal is virgin, untouched and extremely tight, an extremely soft texture. No sexual fluids or lubrication is produced from this young vagina. If the hymen is broken, it will not fit anything bigger than a .5 inch circumference without serious laceration and bleeding, maybe death if it’s too large and inserted with force repeatedly.

   Boy Penis: Small soft balls that aren’t dropped yet. The scrotum is smooth and elastic with few wrinkles. Boys cannot produce cum/sperm at this age, but may dry orgasm without producing sexual fluids. Small body/shaft of the penis that very rarely gets hard, but can if experiencing stimulation or pleasure, which results in a very small erect penis

   Both girl and boy Butt: Small and stretchy, won’t fit more than 1-2 inch circumference into the anus easily. If they’re comfortable, no more than a finger will fit. Inside the anus, the rectum is very tight and soft, wet and clean. They can experience pleasure through the anus. Rectum will not fit anything bigger than an 1 inch circumference without serious laceration and bleeding, maybe death if it’s too large and inserted with force repeatedly. Breasts: Slightly protruding pillow soft chest, otherwise very flat. Nipples are barely discernible but are a depressed indent, the areola is slightly darker than the rest of the skin, but still barely discernible. May cause pleasure or tickling if stimulated. Hair: No pubic hair, no hair on whole body, except on the head. Form: Chubby, round, and puffy. Short limbs, big head. Texture: Smooth skin, silky hair

   Both boy and girl may experience pleasure and explore themselves, they will also learn what’s expected of them with their genitals. Pleasure may be described as a tickling sensation. Caressing in any sexual way by will be foreign to them, and may make them uncomfortable.

   Children 3-5 years old

   Girl

   • Hair: No pubic hair, but may have fine, soft body hair on arms, legs, and back, with the head hair now being longer and thicker.
   • Vagina: The Labia Majora is still small and in the form of 2 smooth parallel bumps concealing the Labia Minora and tender pink skin, The Labia Minora are flat, small and pale, only small ridges that arch above the vaginal opening. The vaginal opening has a thin hymen film covering it entirely. The clitoris is small and obscured by the clitoral hood, around 1/8 inch. Some sexual fluids or lubrication could be produced in the vagina, if hymen is broken and the girl is stimulated. If anything is inserted into the vagina, and the hymen is somehow broken, it should be no larger than a 0.75 inch circumference to avoid serious laceration and bleeding. Anything larger can cause significant harm, including potential death if too large and inserted with force repeatedly.

   Boy Hair: Same as the girl. no pubic hair but fine, soft hair may start to develop on arms, legs, and back. Head hair is likely cut short. Penis: The testicles have grown slightly, and the penis shaft has also grown but still gets hard infrequently, with slight erections occurring with pleasure. The scrotum is smooth and elastic with few wrinkles. Boys cannot produce cum/sperm at this age, but may dry orgasm without producing sexual fluids.

   Both girl and boy: Form: Children at this age still have relatively round faces and bodies, with short limbs, but their proportions are starting to become more slender. Texture: The skin is still relatively smooth, and their hair is soft and silkier. Butt: Slightly more formed and firm than in infancy but still delicate and small. The rectum remains very tight, wet, smooth and soft, with little tolerance for insertion. Any object larger than a 2-4 inch circumference can cause severe laceration, significant bleeding, or even death if inserted into the anus and is too large and is inserted with force repeatedly. Breasts: The nipple is now elevated rather than a depressed indent, with the areola starting to darken more, and become more saturated. Female breasts are flat, with only a slight protrusion, called 'budding'. Male breasts remain relatively flat, without tissue development.

   At this age, children may start to: Practice masturbation and experience pleasure from it. Describe pleasure as a tickle. Demonstrate a growing awareness of and curiosity about sex differences. Engage in sex play, such as playing "house" or "doctor" with other children. Copy adult behaviors and try to mimic adult actions, including sexual. Ask basic questions about sex, gender, and birth, such as "Where did I come from?" or "What is that?" Children may touch their own bodies or other children's out of curiosity, without understanding the meaning behind the actions.

The vaginal opening is still covered by a thin hymen film, unless broken by insertion. The clitoris is still mostly obscured by the clitoral hood but is slightly larger, around 1/4 inch. The vagina may produce more lubrication. The hymen is still blocking the vaginal opening unless broken. The vaginal opening can fit something from 1 inch circumference at age 5, to 2.3 inch circumference at age 8, with a .4 inch radius of fluctuation between different girls. A finger may fit in the vagina now. Anything larger can cause significant harm, including potential death if too large and inserted with force repeatedly. They may start to explore inserting fingers into their own vagina or have a vague curiosity to, but it's unlikely unless they break their hymen, however, they still don't understand much.

   Boy Hair: Same as the girl - no pubic hair but slightly thicker body hair on arms, legs, and back. Head hair is likely cut short. Penis: The testicles continue to grow, and the penis shaft becomes slightly longer and thicker. Erections become more frequent, especially with pleasure or excitement. The scrotum is still smooth but may start to show more wrinkles. Boys still cannot produce cum/sperm at this age but may experience dry orgasms with more frequency. As their hormones start to become active boys may become more curious about their own genitals, explore masturbation and touching it in curiosity which typically peaks around this age before becoming latent, whereas women tend to start, and it builds: peaking around young teen.

   Both girl and boy Butt: The anus and rectum remain tight and delicate, but slightly more tolerant of insertion. The anus can fit something at max 4.2 inches in circumference at age 5, and 6.3 inches at age 8, but for most children it will be less. Anything larger than their individual limit will cause severe laceration, significant bleeding, or even death if inserted into the anus and is too large and is inserted with force repeatedly.
