Hi everyone, who put the crib already? And how much should I start washing baby's clothes? What kind of detergent is best? Gel or regular too normal (they say that powder washes harder) or add more rinsing if you use powder? Did you wash your own clothes and bedding for the first time with baby stuff? So many questions ? I want to anticipate everything)
