4wks old very unsettled in the evenings, and sometimes in the day as well. Sometimes his tummy sounds really gurgly and he screws up his little face in pain, although he doesn't do the whole scrunching his legs up thing, which I've read is supposed to be a sign of colic. If anyting he perfers to stretch out really straight. I am giving him Infacol b4 every feed (I am breastfeeding) which seems to help him burp, but has anyone got any advice for helping his sore tummy/getting him to fart?!
