I was exclusively breastfeeding my daughter for 2 full months until i noticed a large decrease in my milk supply i wasn't producing the same amount as i did when i started breastfeeding.. I spoke to her doctor and started with formula even though i was still latching my daughter to see if i produce more .. And it didnt work so im now giving her just formula, i started with similac since she didnt take the golden infamil , i noticed that with similac she struggled to poop , i spoke to her physician about that as well so she recommended Infamil gentlease, which does help her digest easily BUT she spits up a lot once and a while and im honestly very concerned .. What should i do , i been changing her formula way to much and im just scared to get her atomach bery upset , shes fussy as well what do you ladies recommend..?
