Bit of background to this below but im basically looking for tips on how to help my nephew not feel pushed out by my son now that he has to share his grandparents.
My nephew is 5 and my son is 1. When we get together its usually me and my dh and ds, with my nephew and my dhs parents, the childrens shared granparents (nephew is my dhs brothers son). My nephew has had a hard little life so far, lots of reasons I won't go into but his grandparents (dhs parents) have basically been the only stable thing in his life and they do alot of the parenting and teaching life skills etc.
His mum is single and has a new boyfriend with a son about the same age so when he stays over the kids share a room and he's feeling a bit pushed out at home (lives with mum full time as his dad isn't around but he does have contact).
When we all get together I can see that his behaviour regresses a bit to get his GP attention and he often mimics the baby things my son does to get this, today for example he was fake crying and laying on the floor which is a dramatic example and not something he does alot. He usually will kind of hoard toys or will talk babyish or be extra clingy but in a way that he's kind of side eyeing my son asif to say 'look I won I've got them back'.
This isn't about me having an issue with my nephews behaviour particularly. I can totally understand why he's doing it and where its coming from and relly feel for him. I'd just like to know if anyone has an idea of how we can possibly change things in these situations to help him not feel like he's having to share his grandparents or feel pushed out yet again. GPs are really good at sharing their time BTW and try to get the kids playing together as much as possible so they're not having to chose one or the other.
