My partner and I separated 6 months ago and currently share equal number of nights for our 5 and 3 year old, although I do more daytime care for our youngest who attends preschool part-time. We live a 5 minute drive from one another and have settled on splitting the working week in half and then each having the kids every other weekend, with the idea that the longest the kids would go without seeing their dad would be 4 days. The problem is that the kids refer to the two houses as "your house" and "daddy's house" and it just breaks my heart that they don't consider they have their "own" house. Has anyone else had this issue, and what can I do? Their dad is highly defensive and any discussion about this would no doubt result in a "you're not taking the kids away from me" type of response, so I want to be able to have a few ideas to suggest first.
