Breastfeeding for 4 months now..

Amanda • I`m going through a separation. I have a 5 yr old. Had one ectopic pregnancy back in December. Pregnant with baby #2!!
I've been breastfeeding my 4 month old , and while I'm not doing it just to lose the extra pounds, I am not losing weight.. I'm maintaining... And it's making me a little sad.. lol.. oh and my hair is falling out!?!?
