breastfeeding

I am also breastfeeding 4-6 times daily, and aim for about 1650 net calories a day. I eat back my exercise calories. I find that if I eat less than 1650 cals I feel weak/dizzy/tired. I recommend starting there and if you find you're not feeling very energetic to increase your calories until you feel balanced. I'm okay with only a small calorie deficit if it means I have energy to care for my little one. Slow and steady!
Good luck!

And don't forget to drink water- it helps your milk to let down, and you need it. I never counted calories when I was nursing. My baby brought in a lot of milk by nursing a lot, and I only knew he was gaining nicely, didn't concern myself with numbers. I didn't think I had lost a lot of weight, but when I look at pictures from that time, I was very thin, and I recall I was wearing size 10 jeans. I guess I still saw the chubby me in the mirror. You might look great, even if the scale hasn't moved. But drink that water, maybe it will help with losing weight.

You burn 20 cals for every 1 oz produced, if you know how much you're producing then you can log your calories burned (breastfeeding is under food, it gives you negative calories when you log it) and just eat back what you burn or a little less. You may not be eating enough because if you're getting less than 1700 calories you maybe actually consuming less than 1200 or less than your BMR and actually throwing yourself into starvation mode, try upping your calories by a couple hundred for a week or so and see if you notice any change. I upped mine about 150 and started losing again so it's worth a shot. Good luck!
