I gained 25 pounds while pregnant with my first (140-165). I went back down to about 145 very shortly after birth...and stayed there...until 6 months, when we introduced food. Then I gained about 5 pounds, and when we weaned totally, after 13 months, I gained the other 25 over the next couple months. We got pregnant when he was 2, and I miscarried at 3 months, and lost a bunch of weight--which I attribute to hormones and not to being emotional. I felt quite healthy in all respects. Got pregnant again 4 months later, gained 10 pounds, and, 2 1/2 years later, I'm done nursing #2--and have gained 25 pounds. I am almost up to 200 pounds, when 6 years ago, before baby, I was 140. I know there was a point with #1 where things leveled out and I felt like I was in control again. But, even though I've eaten better this time (the first time, it was like, hey, I can eat ANYTHING! and I did!), I'm still gaining the weight. It's very frustrating. The weird, wonky feelings will go away in a month or two, but the weight gain, for me, took a while to plateau the first time. The second time, I nursed so long (and we just quit) that I'm hoping the weight gain will not pack on a bunch here at the end. I know I was emotional, irritable, and weird feeling when I stopped with my first--after a year. Like I said, with #2, it's been sooo gradual, I haven't noticed the mood effect as much, but the weight gain seems to be the same. I am not a super well controlled person; I feel rotten when I can't eat and I'm hungry--and I AM hungry, like I was when I was nursing. Perhaps you are more in control of those things--good luck! I'm not sure there are a lot of helpful hints in my story, but I at least wanted to say, no, it's not uncommon to gain weight when you wean!
