My nearly 4 y/o DSS lives with me and his dad (DP). He sees his mum very very irregularly (every 8-12 weeks) and only talks to her once/twice a week. Last time he went to his grandparents he saw his mum for an hour. Granted, his mum really isn't in a good place right now and I know shes doing what she can, but everytime DSS sees her his behaviour when he returns is horrendous! Kicking, hitting, spiting, biting, throwing things at me, breaking things, screaming like a banshie, and bedtime has become a constant taking him back to bed up to 10pm for the past 5/6 nights, even wetting himself in his room whilst awake when he's fully toilet trained and is right next to the bathroom. I know these things are semi-normal for a 3/4 y/o but normally he's fairly mild-mannered and we rarely have to use quiet time or send him to his room, he usually goes to bed without any tears. Also usually all of this calms down after 3/4 days but its been nearly 2 weeks and he hasn't shown any signs of calming down. All of this is directed at me as well, rather than DP (although he is hitting people at nursery too, but not going totally nuts like at home). All we can do when DSS gets really bad is pick him up and put him in his room, if he'll even let us carry him without really hitting out/pulling hair/kicking/biting my arms. I'm just wondering if hes taking out what he's feeling about the situation with his mum out on me, because he identifies me as taking her place? I really don't know what to do and I'm wondering if we need to start thinking very laterally about this. I don't want it to turn into a mega problem and us need to go down the child psych route! I'm also wondering if I'm doing anything wrong? I don't shout at him, we say the same things to him (he won't listen to DP btw but he doesn't hit out at DP he just ignores him), we don't have other kids so theres no issues of jealousy there, I'm just getting to my wits end abou this one!
