ok chaps...am I a mean mum? when my 17 week old cries - I don't mean at night when he's supposed to be sleeping, but during the day when I've say, popped him on a play mat for a few mins - I always rush over and pick him up and feel I can't leave him to cry. However, I have read that by his age, a baby should reasonably be expected to amuse him/herself for say 30 mins at a time by kicking on a mat or under a gym so I'm thinking that I might be better to get him used to this by not responding to his every sob. What do you do?
