my 14 week old dd is exclusivly bf and has always fed well. However since wednesday she's been really fussing- refusing the breast and crying loads. She's feeding about 30% less but waking through the night twice (was previously sleeping through). This is really unlike her- she seems so unhappy crying lots and being really fretfl. She's also chewing on everything and drowling- should i call the doctor? her nappies are still regular lots of poos and wees as per usual? any one got any ideas?
