I have similar worries all the time as my boy isn't talking much too. And does flap his arms around sometimes. And does some funny noises. I think it's just very difficult to say what's normal and what's not at this age 😕 and we end up panicking for everything lol.
My little girl does talk a lot and has great eye contact but she also repeats the same sound often (it isn’t a word) almost like she is clearing her throat or has a tick, she flaps her arms all the time and very rarely hugs anyone. She actually gets really upset if my husband picks her up for a hug. I too worry about autism/adhd. It is tricky as so many of these are just normal developmental behaviours. I would like to know how it goes with the paediatrician if you wouldn’t mind sharing? X
My oldest was exactly like this at this age! I am assuming it is normal for some babies, as he doesn’t have autism, and by 2 was behaving completely ‘normally’
