So my DD is 8 weeks old, gorgeous and a greedy guzzeler when she eats (down side she gets really bad wind and colic) she has gone from a slender 6lbs 14 to an ample 11 lbs 3 and now has lost her neck under lots of chins! She is sick a lot and often in the night and gets sick stuck in there. I am constantly trying to keep it clean to stop it getting sore and smelly, but it has got very red and looks sore. I've rubbed some olive oil in, as we're trying not to use any chemicals on her. Anyone had this problem or can give some advice?
