My daughter just turned 2 a few weeks ago. She is an only child and doesn’t see kids that often. She will briefly watch other kids but doesn’t really care about playing with them. She occasionally will follow them. Occasionally will try to copy what they are doing. But like today we went to our friends house who have 2.5 year old and 7 year old and the 2.5 year old just seemed way more social. I did see her offer the kids a toy once. But most of the time she wanted to play with their toys on her own, just wanted to drive the trucks and what not. I keep reading various information on the internet and I really don’t know what to think. Should I be more worried? Is this something that develops closer to 3?
