I can't give you personal "this worked for me" advice because I quit BF before I started to low carb again. I had issues with supply from the get-go. I have heard many of the things to boost supply are going to be carb heavy like oatmeal (and Guiness). Have you tried supplements like Fenugreek and/or Goat's Rue? Cutting calories may cut production though even with these supplements. Make sure you're still eating enough.

@Mami1976D‌ LOL. Yup, hindmilk. I couldn't remember the real term (see, the memory difficulties arent' just yours. LOL). Depending on the age of your baby and whether exclusively breastfeeding, you can know s/he is getting enough by how long s/he is going between feedings, and how well s/he is maintaining on a growth chart relative to starting point (keeping percentages similar, not worried about getting in a better range).

When my daughter was under 9 months old, I still pumped 3 times a day, 30 minutes each, counting set up and clean up. I think I would normally use different bottles each time, but might combine in storage, though not too much, because of wasting that precious fat. I stored in the zipping bags for freezing sometimes, too.

I seem to remember in the little Medela bottles that came with my pump, which if I remember right were 4 oz. bottles, that the hindmilk was 1/8" at low end and up to 1/2" if I combined more than one pumping session. 1/4" was fairly standard for me when combining both sides into one storage bottle either once (my first session of the day and last one were usually more productive, as I recall. I would say as long as you're getting enough to notice the hindmilk and to not have to search for it and worry about how much is there, you're good.

My daughter was always better at extracting the hindmilk than that pump, as she was always more satisfied nursing than taking a bottle from someone else. Btw, she is 14 now, but I did nurse for almost 18 months, and pumping, as you know is quite the experience, so it's pretty etched into my brain. LOL

So long story way too long for others...lol, I would up your fats, regardless of your carb levels, and up your water, and see if your supply increases again.

I think it is just a fact of life that the less you breastfeed, the less you produce. And the pump isn't the same as the baby. I've done low carb while nursing, but also nursed on demand and if I wasn't with the baby, the baby got formula (I wouldn't pump unless I was desperate for it, my body just acclimated to nursing only in the mornings and evenings). I had supply issues with one child and tried every trick in the book, the only thing that worked was Reglan (prescription with terrible side effects). I don't see in this thread if you mentioned the baby's current age, but if he is eating more food, you may just produce less. How are you gauging your change in supply? Has he lost weight? Or just based on what you are pumping?

I had supply issues after each of my six kids, regardless of my diet, except the final one--I ate high fat and lots of it, I didn't exercise hard, and I didn't bother with losing weight. That's right--I chose to be fluffy for the sake of my baby. We made it 11 months before I had to wean her for an emergency dental treatment. After weaning, I intensified my exercise and cut calories drastically, and the weight dropped off.

I think for me, my body started fending for itself in the face of calorie reduction--cutting milk supply was the first thing to go as a non-essential to survival.

FYI, my third baby really suffered between ages 4 mo and 6 mo. He exclusively breastfed, and dropped from the 90% growth range to the 10% growth range. The pediatrician didn't seem bothered, but we switched to formula immediately and he bulked back up. I also noticed NO weaning symptoms in myself, and I feel certain I was starving my poor boy, drying up without even realizing it. When we started him on table food, he ravenously inhaled more than I would eat!! He's a huge 8yo now with no residual trauma. lol.

Good luck! Don't loathe yourself if you find it necessary to completely wean. We hear "Breast is best" and feel guilty for formula use, but breast isn't best if it's not doing its job. In that case, thank God for formula and enjoy motherhood.

My body adjusted really well to morning and evening sessions, I think my daughter was about 9 months or so when she did this, and still was able to nurse on weekends on demand. I was only managing one child, so it was far simpler. @Mami1976D‌ I have to say that no matter how inconvenient it seems to stop and pee more often, if continuing to nurse is important to you, you have to figure out how to up your water. Also, you say that you are so busy with the other kids that you don't have time to pump or nurse (I never really pumped at home, letting my daughter nurse was much quicker). Have you ever considered a nursing sling? You can adjust to to the right settings, set him to suckle, and still keep active/covered and nurse on the go. I have never had to do this myself, but I know literally dozens of real life friends who have done this. I had to enlist my (now-ex) husband to make sure the nursing happened. He had to handle things that we're his normal duties, and he had to lose some sleep, but 30 minutes here or there was something we made the choice to do together. I don't know how your schedules play out, but you might look back and see if anything can change. If not, I'd say you've already done beautifully, and your goal of continuing at least morning/night feedings for a long while is great! You do what you can do. I've always said that the best arrangement for feeding is the one that makes both mom and baby happy - and that isn't always the breast. (hugs)

Try some of the non-carby suggestions for boosting supply. Applying Young Living or DoTERRA fennel essential oil (using coconut oil as a carrier) and massaging into breasts (avoid the nipple area) and armpit areas worked well to help boost my supply (which was crappy to start with, thanks to my PCOS). Also try Mother's Milk Tea/Yogi Nursing Support Tea, Motherlove More Milk extract (essential oil you can add to your nursing tea), Fenugreek (didn't work for me, but works for some people - you need to take a LOT of it though!) I ended up stopping after 3 months because it was such a struggle for me (this was before getting back on the Low Carb wagon, and we'd been supplementing with formula from the get-go because my supply didn't come in right away). Hang in there, Momma! And good luck.

Fenugreek and I were not friends! I ended up making bottles half breastmilk and half formula because my daughter always seemed to want more for a bottle than she did straight from the source. Overall, I hated supplementing, but as it was only part of time, I lived with it...

Haven't heard of most of these others, but I was also breastfeeding 13-14 years ago. I was lucky enough that my company let me split my lunch break to combine with my 15 minute breaks, so I had 3-30 minute breaks and was able to pump three times a day. I took the 15 minute paid break, 15 minutes of my "lunch, then later, 30 minutes for lunch, then repeat the combo in the afternoon. That gave me 3-20+ minute sessions, plus set up and clean up time, and enough time to cram down a snack... @Mami1976D If you employer is flexible at all, you might request this as an option. Pumping all the time sucks, but...it is what it is...lol

Also, have you considered reverse cycle nursing, or would that disrupt your sleep too much?
