DS1 has corrected me since he was about 2, that he is *not* a baby, my baby, or even a little boy. He's a *big* boy (except for when he's a dinosaur, which is reasonably frequent at the moment...).

DS1 just doesn't like it, and he seems to see it as me not acknowledging him growing up and being good at things, being able to do things by himself, etc.

So I've had to stop ... I know he's my baby, and he will continue to be so until long after he has babies of his own - but he doesn't like it, so I've stopped doing it.
