My little one has been sucking on her fists, fingers, thunbs and anything else lately. She is 4 months old and no doubt has started the tething process perhaps but I am also wondering if she is still hungry. Is this possible? She is not a good nurser unfortunately and I question my supply as she has a bad tendancy to suck, stop, suck, stop after she has gotten the let down. When the flow isn't there she gets frustrated and the "suck" is not very powerful becuase she is barely on before she comes off again. What gives? Oh and she tends to be a bit cranky in that she isn't getting milk... I'm not surprised because of her strange routine.
