When to get ready? FRUSTRATED WITH SO!

La • Mommy to a gorgeous little girl ❤️ 12.21.16❤️ Due 8.24.18
When did everyone start prepping for baby, clothes, crib, stroller etc. We didn't find out until I was 13 weeks pregnant well now I'm almost 22 weeks and have nothing and am freaking out! This is our first baby and honestly I'm nervous because my SO really knows NOTHING about babies and he thinks the preparation is going to take like a day or two. SO WRONG! We just got a new house and he's more focused on getting the rest of the house together
