hello I havea 34 months old boy who is shy and quiet. He doesn t speak much. he like to sing but not talk. He doesn t make sentences yet, on word(milk, water, colors, pipi....)he says few words. he likes to look at lights and fans on ceiling and jumps all the time (he stays in one spot and keep jumping for 3-5 minutes) he would do this 7-8 times or even more per day. he doesnt eat much, I have to help him all the time. He is super attached to me (his mother) and crays all the time in daycare. Thank you for the information
