DD1 is 3 weeks old tomorrow, and not sleeping. HV thinks she has colic and reflux. Have tried swaddling, using infacol, ?colysins granules, gaviscon, hold her upright for 20 mins after a feed. She breastfeeds really well, but won't sleep. We were up till 5.15 this morning, refusing to sleep, crying or eyes wide open. Only holding her seems to help but DH thinks she's manipulating us, and needs to be left. Could this be true? What's anyone's experience? Feeling at the end of my tether, tried winding, swaddling, bathing in tummy tub, dream mover, but she hates it. Also tried dummy, but she fights sleep. Seems to give in to exhaustion eventually. Also difficult to know when to actually feed her as she's always ravenous, but I know she's feeding well and there's no problem with my milk. Please help.
