Looking for some advice here as I'm feeling a bit lost.
My partner and I have been together 2 years, I have 2 teenagers, he has 3 and a half year old twins. We have started talking about moving in together, and are pretty much doing so between 2 houses. My kids are happy with the idea, but I'm worried about his kids behaviour. We've just come home from a 2 week holiday and it was pretty horrendous. His kids mum doesn't discipline them, she'll tell them no in one breath and give them what they want in the other. They're quite young for their age, and don't seem to understand when we say things like no ice cream now, have some dinner then ice cream. They'll just throw a tantrum and continue asking even though we don't give in, and never have to their tantrums. Their mum hasn't potty trained them yet, we've been trying while he had them but stopped as she was putting them right back in nappies and we felt it was more confusing for them. We did try the first week of our holiday as he normally only has them for weekends and we thought the long stretch would be a good time to do it, but it was making everyone miserable and we gave in and put them into pull up pants and just kept trying as best we could. Their mum still has them in high chairs, and one of the kids sleeps in her bed most nights. They are lovely kids, great personalities and I love having them in my life, but their behaviour can be appaling, constantly screaming at the top of their lungs, breaking things or turning on taps, emptying the fridge and freezer, generally just running amock any time they were left alone. And when I say left alone I mean for a few minutes to use the loo, get them a drink etc. We generally had one of us cooking or doing a washing and the other watching them if it came to anything longer than a loo break.
Now one of my kids has ADHD and I work with kids with special needs so I'm no stranger to challenging behaviour and have tons of patience, but these kids are just constant, all day every day. And it seems to me it comes down to their home environment. My partner has tried to talk to his ex, but he just gets a guilt trip because he's not their and she's doing it all on her own (she left him then changed her mind but he didn't want back with her). He works away 3 weeks at a time, and he works hard and has the kids as much as he can so it's not like he doesn't take responsibility. But basically anything he says with regards to behaviour and potty training is him criticising her and he's not there etc.
I felt I was constantly saying no or putting them on the naughty spot, moving them away from things they shouldn't be doing while away. My partner can be pretty soft on them, but does discipline them. I ended up speaking to him to explain i felt I was getting no support from him and he had to step up and deal with their behaviour. He said he had agreed with the times I'd given them into trouble and did step up a bit after that, but how do we/he work on their behaviour when they don't get any discipline at home?
Any advice would be really appreciated
