Please can someone give me some advice/tips. My 1 month old son will sleep in his crib in the day and will settle himself after a little grumbling & a little cry yet come nighttime he will not sleep in it. He is nearly asleep when I put him down and he opens his eyes every time and just gets more and more cross. I pick him up and cuddle him and he stops, as soon as I put him down he starts again. This can start at 7pm, 8pm, 10pm or 3am... It makes no difference. He will happily sleep in his chair or laid on our bed so I'm sure its not because he feels unsafe and as I said he will sleep in it during the day. Any ideas please??
