Breastfeeding mama need to lose 100+ lbs. Feel free to add me :)

I don't have experience with IIFYM. But I did gain 65lbs each pregnancy and then lost the weight. I also exclusively breastfed my babies. First, congratulations on your baby! Second, great choice to breastfeed as that will burn calories and really help with your weight loss. Third, ensure your milk supply is kept up by incorporating a few things...oatmeal, fenugreek tea, etc...there are lists of foods that boost supply. A key to keeping supply up is to not use dummies/pacifiers a lot. I'd let my babies nurse even if it was sucking mostly for comfort this is because the suckling stimulates milk supply. It is like they are putting in an order for the next day! So do not limit time on the breast or think it's a bad thing if the baby is just suckling while half asleep and not seriously eating.

Another way I lost weight was via baby wearing...carrying around a gradually increasing lump is exercise. I had various carriers and slings...I went for walks wearing them through forest trails you can't take a push chair along and it was awesome! I would carry them everywhere...grocery shopping, walking in the mall, at home doing chores. The babies loved it.

Finally, not saying your daughter was gaining enough weight, you say she wasn't and I respect that. But wanted to share I had similar concerns with my first daughter. She was born at 51st percentile in weight and height. By one year she had dropped to the 5th percentile in weight and height. Now initially my pediatrician had concerns about her weight gain (as did I) but as time went on, we could see every visit she had grown and had put on weight. My pediatrician felt that it was two things...first the growth charts are based on bottle fed babies which grow faster and it's now recognised they can get too fat so a breastfed baby will lose percentiles on those charts anyway. Second that genetics were taking over...that I'd done a great job cooking a healthy weight baby and now the baby was simply following the path to be a slim petite person like her mummy (me). Third, since she was hitting her developmental milestones bang on time...there wasn't any of the cognitive delays you'd see with a baby that wasn't getting enough nutrition. Well anyway, my first daughter is indeed slim and petite and perfectly healthy . I just wanted to share that because I know with my first baby, I was of the impression that whatever percentile they are born into, they should stay there or get higher to be healthy and it was a complete shocker to me that my daughter could drop so far and still be perfectly healthy.

I breastfead and got into great shape with second baby he was more challenging but it got done for 2 1/2 years .....I would suggest a tablspn of coconut oil daily it kept my milk up but provided lots of good fat also avocados tons of leafy greens especially fennel for milk supply, lemon water first thing EVERY morning!! Green tea at night, cut out sugar (raw honey and organic maple syrup are healthier) you will see a difference without trying I'll do keto and count my macros if you want to add me please do
