Just started weaning my LO a few days ago on vegetable and fruit purees to begin with. (We are under care od pediatrician who advised early weaning at 5 mo due to reflux and bottle refusing). He used to poop once a day, but since we started veg purees 4 days ago, the poos are more frequent (4-5 times a day) and runnier than usual. Could it be fibre in the veg doing this?
