DSC (7&9) arrived at ours last night, they are staying with us for a week whilst their Mum goes on holiday with her boyfriend (apparently going on holiday without your kids is normal these days?!!!)
Well I don't think they'd even been in the house for 5 mins before the fighting and tears and tantrums began! I also have a DS (5) from a previous relationship and DH and I have a DD(nearly 2) together.
It often feels like our normally happy family is turned miserable once DSC walk in, even DH just seems so unhappy and grumpy whilst they're staying with us. I think I could be more patient and tolerant of the situation if he was happy, he says he is, but he certainly doesn't act it!
We have tried different things and in the past we put a lot of their behaviour down to them not being settled at our old house, it was my house before I met DH and it was way too small for us all, so I think they never really settled and there was big rivalry between them and DS, like a fight for the pecking order. We really hoped that moving house and them having their own permanent beds and being able to make their space their own would help to settle them and hoped that things might improve. But it hasn't. Not one tiny bit.
We try going for days out but it usually ends up with me wondering why we bloody bothered.
They are lovely children, I love all our children, especially when I get them 1-1 but when they are all together it's just a nightmare. DD (nearly 2) cries whenever 9yo DSD tries to cuddle DH, DSD and DSS seem to bully DS, DSD cries every 5 minutes pretending that she's ill or injured, DSS throws tantrums like a 2 year old, DS gets angry and upset because he's getting left out of games and picked on.
They're never happy with what we do, where we go, what we feed them etc etc....sometimes I could just scream! But I don't. I grit my teeth and smile.
I know it's mostly normal kid behaviour but I'd say it's on a bigger scale than in most families.
DH used to be a bit of a Disney Dad, he didn't want to spend the little time he gets with them telling them off but he's got much much better over the past year or so.
Anyway, we're going camping next week and part of me is really really hopeful that they will all get on great (or just OK would do), as we're not in our own home I'm hoping that fight for the pecking order won't be so bad. There will be a big playground, animals and a beach to keep them entertained..hopefully they'll love it.
But another part of me is really dreading it. Nearly a week in a tent, possibly with it raining, with 4 kids scrapping and moaning (they moan a lot) could be hell.
I can't even just get pissed as I'm trying to lose weight 
I'm just so bloody knackered, I'm a full time Mummy and also work evenings and weekends. I just want a nice relaxing break. Please somebody tell me that everything will be OK and they'll all love camping and they'll all be best of friends?
Any hints and tips to help them get on would be great too.
