My daughter and son in law have just split.... she has moved into what was their renter home. Kids are 12 and 7 , have been told this is happening for over a year, and parents have taken the split slowly and cautiously .... but now it’s reality, and they’ve accepted the situation. Although the youngest has regressed slightly ,in as much as she crawls into bed with mum or dad , depending whose house she’s in. There are no other partners involved. They have them week and week about , the changeover happening on Sunday around 4 pm, so kids have time to settle in other parents home before school on Monday. Luckily they can do this ,as my daughter has only moved 3 miles from her husband, if and when emergencies crop up they are both there for kids and each other, and as I do the school walk three days a week morning and afternoon, I’m quite a stable influence in there lives. So far it’s working very well, as posters have said, never ,never bad mouth either mum or dad.... positivity moving forward is the way to go on. Good luck with your little one .
