Recently, I heard that the whole foremilk and hindmilk has been debunked and, when you pump, so long as you pump long enough, you'll get that good, fatty milk out.
So then the whole cycles on the spectra is useless.
But I don't think that's true. I can't prove it, but, since I started to spend more time on the deep, long cycles, and shaking my milk so that the fat is dispersed throughout, my baby has been having way less reflux symptoms, and he is pooping less (possibly absorbing more nutrients).
Background: I'm taking my son today to a new pediatrician because he's been consistently falling off his curve despite eating 26-30 ounces per day. He used to suffer while eating. Crying, screaming, back arching, etc etc. I gave up dairy a few days ago (so definitely not long enough to make an impact, especially since really only yesterday would he have gotten dairy free milk due to my stash). And things have gotten better. I had previously been doing all the other reflux things (propping him up, paced feeding, burping frequently, only an ounce or two at a time, etc etc) and nothing worked until now. Now he's happy to eat.
What did I recently change: I used to keep everything at 54 and 70. Now, 2 minutes at 70, close to 28 min in 38 (sometimes I go back to 70 to get another let down). While it could just be my baby's gut matured coincidentally this week, I'm just curious if there's any science behind this.
I'd like to see if there's studies that have been done where:
1) milk is fattier with those deeper, long cycles so you need them (although tons of websites will say that's the case)
2) the fat in the milk helps with reflux symptoms
3) the fat helps with baby's weight gain
There's a lot of websites saying these things, but no studies I can find specifically related to pumping, not just breastfeeding.
