I do. Three bottles of formula (90ml) one in morning, one afternoon/early evening, then one at 10.30pm. The rest of the time I breast feed on demand. I feel she is sometimes not satisfied by breast feeding and can get quite agitated. This evening we gave her some extra formula and she's asleep... This never happens. Anyway just wondering how you work your combi feeding? There is soooo much negativity and guilt on this board about formula and I'd just like to hear from people who are combi feeding. Thank you!
