when did you start buying stuff? I haven't gotten anything yet , I know I have a while to go but I'm like stressing over when I should start buying stuff. I feel like when I find out what I'm having then it will be easier . I've gotten a free pack n play and my grandmother got me a nice changing table , and I think we have a crib but its not definite yet. but when did y'all start buying?
