I’m a bit worried about my 11 month old. Development wise he seems to be quite behind and doesn’t really do much. He started crawling a few weeks ago but he doesn’t wave, point, say any words like mama or dada, doesn’t try and pull himself up/cruise. Isn’t too interested in other babies. I recently returned to work and he isn’t too bothered about seeing me when I collect him. He doesn’t seem very affectionate e.g not too keen on cuddles, doesn't put his arms out to be picked up, just wants to be away playing. He does clap sometimes but not on demand. He does bang toys together when playing. He eats well and sleeps well. He does have good eye contact and has been quite a happy and content baby but recently I have noticed he is a bit more serious and not as smiley. Not currently teething, he already has 7 teeth. I’m just a bit worried as he seems quite a bit behind all other babies I know and reading online he isn’t doing what the milestones say he should be at this age. I have discussed it with my partner but he doesn’t think it’s anything to be too worried about. As a first time mum I probably overthink everything but just hoping for some advice on whether I should be concerned about this.
