Being a bit of a neurotic mum I am wondering how much stimulation/play a 10 wk old should have. I have a couple of picture books which I 'read' to him' a few times a week. A play mat which I put him on when I have things to do and I try to talk to him as much as possible. I do tummy time when I remember too but he tends to cry after a couple of minutes so I turn him back on his back. What does everyone else do?
