My 5 week old is much more lethargic than usual today and has been sleeping all morning and not wanting to feed (either breast or bottle as we are combination feeding). She has had a few small bottle feeds while half asleep but only because I woke her. Is this normal or should I call NHS 111? She doesn’t have a temperature and does feel sweaty unless she has been sleeping on me for awhile. Nappies still seem to be wet.
