I was in a spot where I made things easier for ex because I thought it was best for our daughter. But I had to stop. It was draining me and it wasn't sustainable. Ow as becoming resentful and that' wasn't good for anyone. Eventually I knew my daughter would see I was doing all the work.
Ellie has a great suggestion. He made a big step in making arrangements. If you aren't comfortable, telling him you can give them a few toys if they need, but you think she will be fine using his home. Isn't give him the confidence to spur him in the direction of taking care of things himself.
My ex very slowly is figuring things out for himself when he needs to when I'm not making it brainless for him.
What's best for your D is a mom who isn't resentful of having to do it all.
