I have a 5 week old gorgeous baby who has started to cry inconsolably for the last 4 days. It happens through the day but is worse in evenings. He cries after food, and its high pitched and loud, followed by small whimpers. He arches his head, stomach goes rigid, legs get extended, and he also gets lots of hiccups. I have tried Infacol, warm baths, lots of winding, driving him - and now I am not sure whether he has colic, or reflux. He is mainly fed expressed breast milk about 6 times a day and formula (aptamil) once a day. Anyone got any ideas? Please help.
