I would agree only get if she would use. But I would lean more towards 24. My daughter goes through the 20 plus in a week ( 17 month) but if heavy wetter one might need more or if poops lots. It also depends on if she wants to have a few til diapers dry if hang or line dry like I do on my pockets or if she is going to dryer dry dipes.
