Nursery

Hi mamas! Just a quick question, when did you start getting the nursery ready for your little one? My SIL will be gifting us a crib she never used, brand new and I’m dying to put it together, but I’m just in my second trimester lol. We don’t plan to buy things until after the baby shower. Well, only plan on buying the larger items. Chair and changing table. I just don’t know when to beginning looking?
