I always see ppl suggest that you wash baby's clothes before they get here. I did that with my son, however, after I regretted because even though we bought variety of sz clothing somethings he couldn't fit & they couldn't be returned because they had been washed.wasted $$! What are your thoughts/suggestions? Also, my other concern is what if she is allergic to detergent used? I used Dreft last time, this time it will likely be All Baby and/or Purex Baby.what did you use & was your baby allergic?
