There is mucus in my baby's nappies when she has a pooh. She has always suffered from a bad tummy so I eliminated foods while breastfeeding. She now does part breastfeeding part formula bottles (Cow & Gate Omega Comfort). I have always suspected that she could have a possible lactose sensitivity. She does not have any symptoms to be intolerant but she does still suffer from tummy pains and smelly wind. She does not pooh daily but could go one or two days before having a whopping pooh (or 2). Her poohs are extremely green and quite runny (like runny cake mixture) but I am sure in there also is mucus - has anyone experienced anything like this? Has anyone got any experience regarding lactose sensitivity? Any advice would be great. I have been told about Colief drops - I will be starting these tomorrow I think to see if it helps. I do find my HV's (I have two) who seem to contradict one another. One said to use SMA LF but when I saw the tin it was intolerant babies on medical supervision (my dd isn't) while the other HV said shouldn't use it...? She is 15 weeks and I'm hoping that soon I will be able to find a solution to this to try and help her as she can be quite unsettled during the night with her tummy and its as though she takes hours to try and push her pooh out. Sorry about the graphic descriptions of pooh!
