That sounds like quite a disruptive routine for a little one, to be honest.

OTOH, I'd be devastated if I could only spend every other weekend with my kids.

Are there flexible things you can try? Maybe if she *stays* with you every second weekend, but you have her for some afternoons until after dinner and then take her round to her mums? I know my sister's ex has them occasionally during the week just for a treat for them all, and she appreciates the extra breathing space.

The other thing is, at her age, girls often do start to need more time with their mothers. My dd3 was always a daddy's girl until she was about eight, and then she gravitated towards me much more. Dh was quite hurt by that but I explained it was a normal thing for girls, and that the preferences would come and go.
