DS is 3.5 weeks old and is EBF (had a bottle of formula last night as I was exhausted)
Last few days DS isn't feeding as well as he was, pulling off the breast after a short time, getting angry, throwing his head back etc.
He's also started to vomit after every feed (and even during feeds) - should I've worried?
He's very farty
and it seems as though he struggles to poo (goes bright red, strains, gets angry etc) but this rarely results in a poo. He will do a big poo every 1-2 days.
Does this sound normal? Could it be reflux?
