This happens in my household except my daughter doesn't let my husband change her, and will let me. Our issue is he is the softy and I am the boss. I take the no fooling around, let's get it done approach. I lay her down give her a toy or something and just get the diaper changed, I don't let her up at all, I pin her down if I have to (Never hurting her though), and I just do it, she knows it will be over quickly and at that point she stops resisting. My husband however won't do that and she gets up, runs around, kicks him, the works.. Maybe this sounds familiar to you? Good luck with it though, it's just a phase, try to give her something to distract her. Again, good luck!
