Formula and breast milk; combined feeding.
When Lucas came into the world, my body was still not ready. Meaning my milk was refusing to come in lol. We were in the hospital for 3 days and I tried pumping, but it didn't want to come!! So, Lucas had formula from the start. After we got home, my milk started coming, but very slow. We mixed his bottles half and half for 2 weeks. Sometimes I would pump enough for a whole bottle, but most of the time not. The whole breast milk bottles were a rare treat!! After those 2 weeks my milk ran out and he was on formula from then on. He didn't have a problem whether we mixed his bottles or he had all formula/breast milk. He drank anything in any which way haha. That's my little piggy! :)
