3 week old is combi fed. Although more formula than EBM. He poos almost hourly. But (sorry for TMI) it always sounds worse than it is when you open his nappy. It's a mustardy orange colour & there's never really much there, almost like a shart more than actual poo. He defo suffers with tummy pain & sometimes he will manage a couple of farts, although clearly not constipated. It just seems a lot to be poohing...any one any advice? TIA!
