I actually don't know that H really wanted to pull his 50% share as much as he wanted it to be easy. He didn't want to have to keep track of something like a 3 4 4 3 schedule, he specifically called that "ridiculous". When I suggested something way less than 50/50 he readily agreed, gave no pushback whatsoever. My thought was to disturb D11's routine as little as possible in the beginning and then increase overnights with dad until everyone was comfortable. This isn't a legal agreement so we can change whenever we want.
