Could do with some advice. DS (3.7) has been a handful the last couple of weeks. He's always been more attached to me than DH, eg. will say he wants to sit next to me at the table or wants me to put him to bed. However the past week or two he's started being quite mean to DH, eg will completely reject DH (complete with crying and pushing him away) when DH tries to do something for him. He has also told DH a few times that he doesn't like him.
I'm at a bit of a loss about what to do. I've tried pulling him up on it, eg. telling him he is not being kind and that he is making me and DH feel sad. We've been consistent with insisting that DH looking after him on certain occasions, eg if it is DH's turn to put him to bed (although this usually comes complete with a tantrum).
He has also been asking to sleep in our bed a lot (despite never having been bothered before). We did let him a couple of times, but with DD (6 months) in there a lot of the time too, there was no space and everyone had a bad nights sleep. So although I feel bad about it, I've told him he can't sleep in our bed. DH has slept on DS's floor a couple of times when he's woken in the night (DS strangely accepted this). What do other people do in this situation? I'm exhausted as DD wakes every couple of hours in the night and cosleeping with her is the only way I get any sleep.
