Hi, I'm married and 10w pregnant with first child, DH has a son aged 6 who stays with us every weekend and half of all school hols. Things have been great with nice amicable relationships between all parties. DH's ex is engaged and her partner is lovely and really good with DSS.
DSS is normally a really polite and well-behaved boy, so much so that we've not ever really had to discipline him, i.e. no naughty steps etc. He is the kind of child you can have a reasoned conversation with, explain consequences, others' point of view etc if he does something which is slightly naughty and he will understand and not do it again. The rules we have are pretty basic, mainly do as you are asked without being cheeky/stalling, eat only at the table, don't jump about on furniture, tidy up stuff you've got out. DH and I are very careful to also follow these rules and be good role models.
However, in the last few weekends, he's been much more difficult. It may just be me getting all stressy because I'm envisaging a future with a tiny baby added to the mix - please tell me if this is the case! DSS doesn't know about baby yet so it's not something that can be affecting his behaviour. He has started answering back, telling us to wait when we've asked him to do something (even if we've given him a 2 minute warning), ignoring instructions, grumbling, and what worries me most is that he's suddenly become really boisterous and literally cannot sit still for more than 30 seconds. This is not an exaggeration! He used to be super-sensitive and scared of lots of silly things but is now more confident - this is obviously good but I'm not sure about the physical manifestation! It's got so bad that he seriously injured his mum last week - she was taken to hospital in an ambulance and is now immobilised for 6 weeks. I've invented a permanent tummy-ache so that he doesn't involve me in his crazy leaping about and hurt me. Unfortunately his dad loves that kind of thing and it only ends when one of them is injured...
Anyway, my issue is that I am picking up on this and I feel that I'm constantly nagging at DSS. This is partly because the instances of jumping on furniture/not tidying up/answering back are getting more frequent but also because he's not responding to the first warning any more. I mentioned this to DH, the fact that I feel awful about constantly being on DSS's back and asked DH if he thought I was being too harsh and he said that he agreed with me every time I said something and backed me up. I told him that I felt we should share the discipline (as we always used to) and although he says he agrees with me he added that he doesn't realise that DSS is being naughty until I've highlighted it and by then it's dealt with - he feels that stepping in at that point would undermine me.
I feel that I want DH to take an equal share of the discipline, I have been in DSS's life since he was 1 and DH has always been really careful to involve me on a 50/50 basis in terms of 'parenting' while DSS is with us. The situation is either that DH is overly relying on me or that I'm more stressy/sensitive because of new baby or DSS is getting more challenging. I just can't make up my mind what's happening - help! I feel that I'm wrecking my relationship with DSS :(
