DD2 is 8 mo, and for the last two weeks she has had very soft (and sometimes runny and mucasy) poo. From when I started weaning her, her poo has always been a good shape and consistancy. Her father and grandfather both have ceoliac, so I cut out gluten a week ago, but it doesn't seem to of made a difference. She also dropped two centiles (from 75th to 25th) between 6 and 20 weeks.
Does this sound like an intolerance to something? How long does it take from when you cut something out to when you can notice a difference?
