We live 5 mins from my in laws who have a really big house.
I'm going away on a business trip for a few days and we've all decided it's best that my kids ( 2 and 4 ) stay with in laws during this time.
They've not had many sleepovers there, but they absolutely love spending the day there. My oldest is dying to sleep over.
At home, I tend to sleep with my 2 year old and even my 4 year old often comes to find me in the night. She's happy to sleep with her dad too or with both of us. The 2 year old is more mummy specific.
Anyway, my H won't be able to drive them to school/ nursery, but may be able to put them to bed on some of the days. I mentioned it would be good if he also stayed at MIL house. The kids will inevitably wake up and it will be nice for them that their dad is there. Even if he can't be there at every bed time. They could make sure little one sleeps in dad's bed. So when he wakes, his dad is with him.
He doesn't want to do that and just wants to sleep at our house. Even the night he can do bed times, he would just leave them there and come home after.
