Very small snot suckers! I had a few, thought I was prepared, but no. The ones you just go buy are too big to fit up their noses! You have to look for a really small one. That's one thing I always remembered to tell new mothers. There I was: first night home, miserable, baby screaming, a snake in the bathroom, and a snot sucker that wouldn't fit up my newborns nose! Hahaha
