breastfeeding moms

I would suggest maintaining until your supply is firmly established, then maybe drop down to .5 a week, then 1 a week but watch your supply as you lower your calories. Make sure to log that you are breastfeeding!

Just make sure you are getting adequate nutrition and fat! Baby needs your milk to be as nutritious as it possibly can be, and it can't go in your milk if you aren't eating it. Try to skip nonfat or "diet" foods.

ETA: It seems safer to just eat at maintenance and not log breastfeeding. That will create it's own deficit and you don't want to risk baby's supply or nutrition.

How old is baby?

I have my goal set to 1lb a week and then add 500 calories to my food diary (Search for "breastfeeding" and there are several options) which shows as negative 500 so it adds it to my daily goal. I usually eat around 1900-2100 cals and my baby is 7 weeks old. I've been doing it since 5 days postpartum... my weight loss in my ticker is from that day to now.

I think it's actually really hard to calculate.
Children feed in completely different ways, as with everything else baby related. Your body will also react differently.
My firstborn was ALL about the milk. She fed so much I was hungrier than I had every been in my life, including pregnancy. I had to learn to bake as I was getting through serious numbers of cakes a week. I still lost about 2 1/2 stone. The biggest losses came after a year though as older children have bigger bellies to fill. Annoyingly, my second child was much more relaxed about milk and I put on all the weight I lost the first time.

In general, aim for maintenance, aim for healthy living. Don't do any drastic dieting and see how your body responds. In most cases, the body will prioritise the milk production over your health, just as in pregnancy. It takes serious malnutrition (for you) to significantly alter the composition of the milk. You'll feel like crap though if you're not eating enough good stuff.

As Rawcarrots says though, it's a tough time having a young baby / child. Be kind to yourself and listen to your body. Take care of it and feed it good stuff when you can, get good snacks around for those days when you're too busy chasing your tail to cook well, or those bored 'itchy mouth' moments where and if you properly have The Hunger, eat.

exactly as Flafster said. My little one is 9.5 months now and only feed 2-3 times a day and if he wakes at night, hes almost full weaned onto food now (blw) at the beginning g i didnt count calories or anything until we started weaning about 6 months? And i lost almost a 1lb every week, to me that was my time to enjoy just being a post birth mummy and when he wanted food it was like oh ok he's getting older now, im "allowed" to and should do something else , so i just cut out junk which helped and i still lost 1lb a week from then on, its been the last 2 months ive only lost maybe 1/4 of that , enjoy your boob feeding journeys , little one definatly seems to be losing interest more each week

i wished i had seen this thread when i was nursing my youngest. my body latched on to calories when i was nursing. my advice would just add 500 extra caloried and make sure you add that you are nursing like pp have said and when you get to the point where baby isnt nuring much anymore or when you wean then i would drop your calorie count.
