Anybody plan on breastfeeding and formula feeding? I'm at FTM and want to breastfeed for a couple weeks to make sure he gets the colostrum and also some milk but when I go back to work I want him to be on just formula because of my job and hours. Any tips for this? I don't wanna cause colic or other problems by doing it the wrong way. Can I just start with both from birth or do it another way? Thanks!
