My newly 14 month old isn't pointing either and I have given up looking at signs as it stresses me out and the LO picks up on my stress and worries. He has been walking for 3 weeks though and I think he is busy getting used to the idea of walking and exploring instead of communicating and socialising.
I've just seen a video of a friends baby similar age to my DS (3.5 weeks older) and he is pointing, sharing toys etc but he has been walking since 10.5 months and he has a older toddler brother where he gets to see the more advanced baby behaviour whereas my son, has been in lockdown for 3 months (like everyone else of course) , recently started walking and is an only child. I can't take him to the nursery right now so he could spend time with other children and what he learns is from from me and DH and sometimes I realise we don't really sit and play with him properly being busy with house chores and working from home etc.
But from today, I will spend at least 1 hour sitting down with him and engaging with him properly. I was a late speaker and developer too when I was young but NT and managed to get a masters degree and work in a managing position, ok, I wasn't the most brightest but I'm practical and with determination you can do it.
I'm not saying people with autism can't, of course they can and some of them are really good in certain fields but what I'm trying to say is; if my son is similar to me and with the right support and guidance he too can achieve what I achieved and have a decent living. He doesn't need to be in a rat race amongst his peers of who hits their milestones first, it's more about their life afterwards. No one will ask you about your milestones when you are in your 30s but people will either look up you or look down at you and that comes down to the individual.
You may see some people who were very bright when they were young but a couch patato living on benefits smoking crack and you may meet people like myself not the most intelligent, late speaker and developer but was determined to make the most out of the opportunities I was given (brain, education, family support, family guidance)
