Ds is 11 days old and for the last 24 hours has gone from being quite contended and feeding really well to a cycle of being breastfed, he is a really good eater and putting on weight fast and lots of wet and dirty nappies, falls asleep on my boob and before he would happily settle in his Moses basket he now wakes after ten minutes screaming and thrashing and usually with hiccups, he then wants feeding again mainly for comfort, he is not a burpy baby and used to settle after lots of farty poos but that's not working now, he gets really red and cross and will only settle when back on my boob, last night we repeated this cycle every twenty minutes or so, if it is comic should I try infacol?
