Is it my responsibility to provide everything?

My daughter is a year old and just now going overnights w her dad. He wants me to buy a car seat for his car, diapers for his house, food for his house (which if she was on formula I would understand but she can eat pretty much anything.) He wants me to buy a bed for his house, a pack n play, a set of toddler dinnerware and sippy cups. I understand that I’m the custodial parent and I have her most of the time but he is her parent too and I don’t feel like I should have to supply everything other than diapers and clothes, the basic stuff and stuff she definitely needs. He thinks bc he pays child support I should be buying all of this but child support doesn’t cover everything. When it comes down to it I will buy these things for his house if he truly won’t, but I do feel like he should be better prepared if he wants overnights. Idk am I wrong or?
