As much as I hate using formula (I really wanted to exclusively breastfeed) I have to say, using a bit here and there (no more then 1 maybe 2 bottles in a day and not everyday) has been so helpful. I still breastfeed him as much as possible and try not to use formula. (I don't judge formula exclusive mommas) I just love breastfeeding him and I know how beneficial it is for the both of us. But seriously, formula gets us through long car rides, traveling, or when I have appointments. 🤔😄
