I happen to believe (and have finally learnt, in time for a successful 4th marriage) that marriages work best where each partner leaves the other to be themselves where it comes to how they dress, and how they interact with others etc. etc. That means that when there are times you have to pull them up about how they treat you it doesn't come on top of a load of other criticisms they already resent you for and get ignored lol. So I disagree with those who advise you to try and change him or "get him help". Anyway, he has decided to avoid the small children and they and their parents will form their own opinion of him and he'll have to live with it. That's why I say don't cover for him. There is no need for you to be seen as colluding, you should enjoy your honest relationship with your family.
