My 3 year old daughter loves to play her building blocks. Even my 10 month old daughter too tries to reach for toys everytime my eldest will start to play. She never cried when taking them away. She is also stacking blocks now, I am not sure if she is too early to start this kind of maybe; if yes, I think she is advance. She is only 10 month old and I am very much careful of what toys that she can play. Small objects are dangerous so I’ll prefer big blocks as what my eldest playing too.
