I am 30 weeks tomorrow and I just started doing my big shopping. I started buying little outfits and stuff when I was around 20 weeks. Now I have my car seat, travel system, crib, bassinet, and pack n play :) waiting for my baby shower then I'll buy whatever else I need and start packing bags for the hospital :
I started baby shopping at 13 weeks with my second and with my first i started at 24 weeks. Its never to early. I say go wild and have fun buying baby clothes
