i play. by green sprouts Boys' Snap Reusable Swim Diaper

My almost 2 year old is 25 pounds and wears a 2t/3t pull up. Should i go with the 48 months or 3t size? Her little thighs are kinda chunky

The size chart lists months but the drop down lists small, medium, etc. how do i know what to buy for my 10.5 month, 20 pound baby?

Does this listing for the white swim diaper include one or two diapers? It looks like one, but then the price says "$15 ($7.50/count)"

I ordered these in march and it’s still “on the way”. my baby won’t be needing them anymore since summer’s almost over. when will i get a refund?
