DD is almost 4 months. Going back to work early May so introduced bottle of formula during day and continued BF in eve and overnight. DD has taken to bottle and drinks 4oz each feed. Tonight she was really restless on the breast and fed several times on each side but took a while to settle and go.back to sleep. This is unusual for her. She winded and brought a little milk up so I know she is getting some. I am paranoid now that my milk supply is dwindling and she is not getting enough. Breasts are no longer hard (sorry if tmi) and so no idea if they still fill up... please reassure me. I don't want to stop BF when I can. I also have a sore throat and have had for about a week. Could I be dehydrated? Am on ADs too... could this be a factor? Any advice ... including advising to go all formula feeds if you think thats best for DD welcome. Thanks for reading.
