Your body goes through massive changes during early childhood, and it's pretty amazing how quickly everything develops! Both boys and girls grow at roughly the same rate between ages 3-5, with steady increases in height and weight becoming the norm.
Bone growth is particularly important during this stage. Your bones don't just get longer - they become much stronger and more rigid too. This means you need plenty of calcium in your diet to support this crucial development.
The combination of growing muscles, developing bones, and increasing brain connections makes movement far more accurate than before. Simple activities like running, jumping, and catching become much easier as your strength improves.
Key Point Maintaining a healthy weight during early childhood requires both a balanced diet and regular exercise - it's all about finding the right combination!
Early childhood is when your brain becomes like a super-powered learning machine! Curiosity drives everything - you develop an intense desire to understand objects and how the world works around you.
Memory and fluency become major players in your development. Memory helps you recall information from past experiences, whilst fluency allows you to express your thoughts easily and accurately.
Between ages 3-4, children master some brilliant skills
Key Point At this stage, learning happens best through touching, exploring, and asking "why?" about absolutely everything!
Language development follows a fairly predictable pattern that's genuinely impressive to watch! At 2-3 years, you start making two-word sentences like "toy gone?" whilst building vocabulary around familiar objects.
By age 3, simple sentences emerge "I want food!" This quickly develops into the question-asking phase where "What's that?" becomes your favourite phrase. Your knowledge base expands rapidly during this period.
At 4 years old, strangers can understand your sentences, though mistakes like "putted" instead of "put" are completely normal. By age 5, correct grammar becomes standard, and formal language skills continue improving steadily.
The progression continues impressively 3-year-olds change conversation topics constantly, 4-year-olds hold proper conversations and can argue their point, whilst 5-year-olds enjoy rhyming games and start putting sounds together to create words.
Key Point By age 6, most children read simple stories with genuine enjoyment - showing how quickly language skills develop!
Learning to handle your emotions is one of the biggest challenges of early childhood, but it's also incredibly rewarding! By age 3, you become much better at coping with feelings and start developing a self-image.
Independence becomes a major goal - reaching that stage where you can care for yourself and make your own decisions. Your emotional wellbeing still depends heavily on secure attachments with caregivers who make you feel safe and content.
During this period, you experience new feelings like love, hate, fear, and jealousy for the first time. Learning how to deal with these emotions takes practice, but it gets easier as your language skills develop.
The brilliant thing is that as you learn to express feelings verbally ("I'm sad"), caregivers can better meet your needs. This creates a positive cycle of security and contentment that supports healthy emotional development.
Key Point Forming wider relationships at nursery or school helps build emotional security beyond just family connections!
Social development really takes off as your language skills improve, making it much easier to interact with others! Your social circle expands dramatically when you start school, moving beyond close family to include friends and teachers.
The way you play evolves significantly during this stage. Social play begins around age 3, marking a shift from playing alongside others to actually playing together cooperatively.
This type of play involves sharing toys, doing activities together, and participating in organised games with shared goals like board games. Through these interactions, you learn what behaviour is considered acceptable in social situations.
These new relationships - both close friendships with other children and more formal relationships with teachers - become incredibly important for your overall development and sense of security.
Key Point Social play teaches crucial life skills like cooperation, sharing, and understanding social rules that you'll use throughout your life!
