Both my daughters were very pukey! I was forever changing outfits for them and me. It didn't seem to bother them and they gained weight quickly so we just left them to sort things out. They did outgrow it In fact I remember the first time they burped and they didn't puke. What a great day! They were both over 6 months.

The one thing it did affect was...I didn't put them on their tummies for play time as they only puked more. They never really did that rolling over thing and didn't crawl in a normal way. They did a scooting thing instead. They are both normal girls now so don't worry.
