She does look like a small girl! Do you have her on unlimited kitten food? She’ll need to continue with unlimited dry food and meals of wet food while nursing too. Now is also the time to get some kitten supplies. The basics are kitten milk replacer (powdered is best), a needleless syringe in case you have to supplement, and a kitchen scale that weighs in grams. Do you have nest options set up? And have you looked into a plan to spay your girl in two months? It’s not a bad idea to make the appointment in advance.
