Have to agree with procrastinating.
My DCs feel rejected by their Dad at the best of times. His new DP has 2 kids and they can not understand why he spends more time with her kids and not them.
In their words - they have stolen our Daddy, they have one they do not need two.
When they go round to his new place,(a rarity) they feel sidelined. I hear the old disney dad thing - but they want quality time with their Dad. Happy to do stuff all together as luckily most of the kids get on and play, but they want to do just them and Dad as well - that is not disney, just kids.
Simple things, they want to snuggle up on the sofa with Dad, not allowed to, as he sits next to her always. They want to sit next to him if they go out - not allowed etc etc. They see him so little, I am not saying pander, as rules are rules whatever house and they know that = but the newfamily has to give them some space aswell.
New baby on its way and they are not happy. Eldest is 6 and he said - well that's it Mummy, she has won him and we will get nothing. Sadly I can see that as being true. New baby's stuff has been put in the room they use, they are going to have to move up into the loft - all stuff which just adds to their insecurity.No photos of them around the house - just her kids, they are starting to notice.
Do Ex and his new DP talk about the baby with them? - No. I am left preparing them for the arrival -which I am not allowed to know about when, it is coming, when they will go and see it etc. Her DCS have seen scan pics, they are not allowed to.
AM sure her own kids are insecure as well, but they are exposed to new baby coming stuff all the time - I can see mine have shut it off in their brains, will occasionally come for a cuddle and ask a question, we look on the internet about babies and new brothers and sisters but this is not my job....
