My son is now 4 weeks old and in the last week and a half keeps crying all the time if not in my arms and/or at the breast. Attempts to let him self settle fail almost all the time as his cry only increases to the point there are actual tears down is face (although I thought actual tears not common this early). I am putting baby on the breast with less than 1 hour interval as a result. Hope not a problem with the milk (last time he was weighed - week and a half ago - he had put 400g in 6 days and continues to have a lot of wet and also dirty nappies). We are on demand feeding, although cannot tell hunger from need of comfort. Does not take dummy. He only seems to be happy when held in my arms and most of the time attached at my breast but I fear for consequences long term. Should I be insisting on self settling? Or shall I consider the possibility that he may not be getting enough from my milk? Any advice? Any similar experiences? Thanks.
