Re: 4 1/2 month old fussiness while nursing
Normal 4 month old stuff. It may have to do with teething, or distractibility, or perhaps a normal adjustment to supply that has made letdowns happen a little slower. If it's a letdown issue, just put up with the fussiness, keep nursing, and let baby learn how to use his nursing skills to get the flow speed he wants. Often moms try to "fix" letdown issues- and that's counterproductive to the baby's learning experience.
