Would love experience and advice please.
DD has been very unsettled - mostly at night between 9pm-7am.

She will be fed, dry and burped but continues to cry , jerking head movements, pulling at face, arching back and bringing knees to chest. eventually i have to let her nuzzle on my breast to fall asleep (she doesnt feed at this point just plays) or put my little finger in her mouth to help soothe.It will take up to a hour after a feed to settle her and then we are lucky if she sleeps 30-45minutes before waking again.

I assume it is wind pain?

Is it possible it is something i am eating... are there foods which i should avoid?
is there any holds/techniques to settle this pain?

We always put her in a dark quiet room at night, bath before hand, when i feed her i keep her swaddle and dont stimulate her any other way, keep lights dim etc but it doesnt seem to work.

Is this just what happens with newborns and we need to stick it out?
Should i introduce a dummy for comfort?

thanks
