DS is 22 months and is yet to talk. He babbles but doesn't actually say any words. I've recently taught him to wave goodbye and he will copy me and his sister if we clap, so he does do that. He's quite placid and plays independently and is very smiley, giggly and affectionate. But still, he doesn't talk. My DD started talking early so this is unknown to me. He puts objects in his mouth/licks often and doesn't point at things he wants either, which I've read is a red flag for Autism. But then, I've never taught him to point and if he wants a toy or his water on the side, he generally just goes and gets it himself so I don't know. I phoned his HV today as I'm quite concerned but she didn't seem too bothered and gave me some tips to get him talking but they won't investigate further until his 2 year check. I'm confident his hearing is ok as he responds to loud noises and will turn and look at me if I call his name (unless he is engrossed in Peppa Pig, then he ignores me!) Should I be worried? The HV said this is very common but of course you worry when it is your own and I am wondering about Autism etc. Any advice appreciated. I should probably add, both my nephew and my brother didn't speak until they were 3, not sure if this can be hereditary?
