When to buy the crib??!

Tehkeeyah • I'm a army wife and this is my second pregnancy. I had a miscarriage and hoping this one is a healthy baby
I'm currently 5 months and I keep thinking I'm running out of so much time 😥. I keep thinking I need this and I need that like right now. I know for sure no one is going to buy me a crib for my baby shower so I'm just curious when did you guys by your crib ?
