We are pretty much ready with everything we need for baby, but I just realized we only have 5 burp cloths (and no laundry in apartment...). What is the sweet spot for burp cloths assuming 1/week laundry trip? We have lots of little flannel receiving blankets and 12 A&A blankets, but I think we will definitely need more burp cloths...I realize every baby is different, but what has worked for you?
