My DD us 4 weeks tomorrow and teh last 48 hours have been hell. She will only settle on the breast - she just eats and eats and eats, she has only slept about 5 hours in the last 24. I don't know what to do I cannot face another day of constant crying and feeding, I'm exhausted. She is quite wriggly - could it be colic? If so what do i do? Have others had similar experiences? will this phase pass? I called the NCT lien and they suggested she was using the breast as comfort - if so should i take to a doctor? She seems very well and producing plenty of nappies. I feel so useless as I cannot seem to fix whatever is upseting her. :-(
