I did mine at 34 weeks :)
Okay i just dont want his clothes to sit in his dresser forever but i want to get everything done so i can relax when im closer to my due date!
Been wanting to get it done since 33 wks but finally did it yesterday at 37wks. Lol.
It doesn't matter when you do it, if you're worried about it still smelling good, take some cheap bath salt and those little netted party favor bags you know? Put the salt in the bags tie them.tight and drop one in each drawer. It works awesome!
