My son is 10 months and one week old. He cannot crawl and cannot cruise although he has started to sit up by himself and is working on pulling to stand. He responds to his babe if I’m far away enough or go into another room, but doesn’t really respond if I’m sitting right next to him or if he’s outside in the stroller. He doesn’t point, doesn’t imitate, doesn’t wave. He doesn’tplay peekaboo back with me ( he smiles but doesn’t imitate). He smiles from time-to-time but it takes a lot to get him to smile. He babbles but it seems more to himself than communicative. I’m concerned- I’m a ftm so naturally I’m worried. Please share and advice or experiences- thank you!
