Since Wednesday, my 4 month old baby has had a change in the frequency and consistency of his poop. It’s yellow, but seems to be quite liquidy with some thin chunks. And he’s pooping after almost every feeding. He acts normal otherwise, no fever, no vomiting (except once on Wednesday night) eats normal (formula fed), hes been on the same formula for over a month. and has regular wet diapers. I’ve been messaging with a pediatrician and says not to be worried if he’s not experiencing other problems. It’s just been about 5 days. Any input??
