I washed eerything after my baby shower! The clothes issue was kind of a tough 1 for me! I wasn't to sure how soon I should wash them or how much I should wash. I washed about 10 new born onesies & 4 sleep outfits. & a few 0-3mth clothing! Being that I am not sure how fast baby will grow & the rest of the clothes I kept all tags on them incase she doesn't get to use them & I can return them for bigger sizes! Also make sure you use baby detergent. I washed all blankets, bibs, wash cloths, & other stuff tho! Being that I am a 1st time mommy I worry about everything!
I started like a month before...you never know if your gonna go a little early :)
I did it after my baby shower. That way I was prepared and wasn't feeling so fat!
