buying baby items while ttc

Brittany • TTC 2nd child, on Metformin for PCOS
I just wanna know if I'm the only one who is really wanting to get a few baby items while ttc. just like things that are on sale. was at goodwill last week and found a changing table for like 10 dollars but talked myself out of getting it. am I crazy to want to stock up on a few essentials?
