What size clothes?

Kim • PCOS,fibroid fighter!💪🏼 Mommy to my beautiful 3 yr old girl! our 🌈 baby girl born feb 1st 2018 🎀 💖💓💗🎀🎀

So this is my second baby, but my forst was very small ( still is) my doctor told me this baby is going to be bigger! So this is a like starting over for me. My first was in newborn diapers for 4 months if that tells you anything. I️ guess my question is what sizes are you getting and what type like more foot pjs and long sleeve onesies? I️ thought I️ would be covered since I’m having another girl and they will be 3 yrs apart exactly, but I’m realizing if they are different weights I️ can’t use all the same things!!
