Hello. We have a son (12 weeks old) and a daughter (23 months). My partner is still breast feeding our daughter as she has been convinced of the benefits of continued feeding. Our son was tracking the 91st percentile consistently and doing one custardy stool per day, until about three weeks ago.
Our daughter got a cold of which our son exhibited some symptoms. His stools instantly turned a very wet consistently and became extremely frequent i.e. diarrhoea. Since birth he has often seemed agitated (regularly tensing up and throwing his limbs about angrily), but has remained otherwise in good spirits throughout. Initially we put the diarrhoea down to the cold and expected it to pass within a week, however it didn't.
After a week we went to see a doctor who said it would only become a concern after two weeks. Shortly after this his stools turned to green. We went back to the doctors after two weeks and had a stool sample taken for which we expect the results on Tuesday. However the doctor expects a negative result with no sign of infection. Inspecting his stool and seeing him in a good mood, she seemed confident it was the result of too much fore-milk.
However we have already been aware of the potential to miss out on hind-milk so my partner has been trying to intentionally make sure he gets a balance and to cut our daughter's consumption back. After the doctor stated her opinion she has been trying to up the balance of hind-milk further, but this doesn't seem to be improving the stool colour, consistency or frequency. She believes it is still getting worse.
He has dropped to the 75th percentile but is still gaining weight
We have also come across threads where other mothers who are tandem feeding have experienced similar troubles and the opinion seemed to be that there isn't much you can do about it but wait. However we are concerned that he is missing out on nutrients at this crucial stage of development.
We thought it might be best to quickly ween our daughter so that the milk is tailored exclusively to our son's requirement as his need is greater. But are reluctant to give up on the benefits for our daughter. This will also be tough - she loves her milk. And besides we have no idea if this is how it works.
We also have no idea how much of a problem this is for our son. It certainly doesn't seem at all healthy and is regularly causing a sore bum.
Any input would be much appreciated.
