My mother in law watches my son a day a week. He's two years old and very chatty. He's recently started calling our house "daddy's house" I didn't think much of it until I heard my mother in law refer to our marital home as "daddies house" to him when we were travelling home recently (without my partner) and again at a family party whilst speaking to family.
I mentioned this to my partner and he doesn't see the big deal but if I'm honest it's not sitting well with me. To me it sounds like our son lives with his dad rather than with his family. Not that it actually matters but our house is jointly owned by the pair of us and we worked very hard to get our deposit together a couple years ago.
Would I be unreasonable to ask that this stop and they simply refer to our house as my son's home? Or am I being oversensitive and overreacting?
