My son is 3 in a couple of weeks. He has always been more of a mummy's boy which is understandable as I'm the primary carer out of the two of us (although still work 30 hours myself so hardly model mummy!). DS's behaviour to daddy has got increasingly worse - particularly if he wakes at night at which point he will scream the house down if daddy tries to go near him. Just had an episode now and I refused to let him go back to bed until he told me why he was being so horrible - a variety of answers but largely along the lines of it makes him happy! Cue worrying thoughts about devil child.....DH has started a new job and is working long hours, and I am also 4 months pregnant with number 2, which might be having an effect. Any advice on what to do - it's horrible for DH and very frustrating for me. He seems generally fine with daddy if I am not around at all....perhaps I should move out and leave them to it?
