growth spurt

i dont think mine went away or lessened. i think she was just hungrier so it seemed like i had less

no. growth spurting babies suck a lot in order to build supply. it takes a day or two for the body to meet the new demand that's all, your breasts are never really empty. I also never fell a letdown unless I'm a bit engorged and even then only once.

foremilk / hindmilk only happens if there is space between feeds and the fat in your milk has a chance to cling together in your milk ducts. because a baby feeds closer togrther in a spurt the milk is more uniform as it does have that time. its all the same milk though.

It is common for mom to not feel the let down sensation as much as baby gets older, some don't feel it at all. At this age the postpartum hormones are beginning to stabilize and your breasts may start to feel softer, feel let down less etc. It is just your body getting more efficient. How your breasts feel is a poor indication of milk supply. It sounds like you are doing a great job of following baby's lead, feeding on demand, letting baby decide if she needs one or both breasts etc. Keep following baby's lead and as long as she is still peeing and pooping and gaining weight then your milk supply is just fine!
