gain, but at a loss.

Well, Cate's appointment brought good news... I guess.
She's up to 13lbs 0 oz. - a 6 oz. improvement from her highest weight.
BUT- she's been up many many times a night every night since Monday. Last night, I'm fairly confident that she didn't sleep at all. I've been nursing her 3-4 times / night, when usually she doesn't nurse from 8p.m. to 6 a.m. I think that has more to do with weight gain than anything else- and I cannot continue it! It's encouraging that she is indeed able to grow, but I feel like she's eating non-stop, day and night, always spitting up, always having this massive round belly.
I'm not convinced, and I don't think the doctor is either.
We go back in one week for another weight check, and if it's another significant gain, we'll spread out our visits to once every two weeks. We didn't discuss if it's not...
I just don't know what's up with Cate- this not sleeping, constant fussiness, won't let me put her down ever at all for any amount of time. I don't know how people do it, when that's just normal for their baby. I'm praising God for the easiness of both of my newborns.
Anyway, I'm running on empty. I went to bed at 11:30 and was up at 12:10, 2:00, 3:30, 4:50, 5:30, 6:15... And my house is a messy mess and we have friends coming over for dinner, which means no nap for me. So- I probably better get to cleaning. just thought i'd let you know that Cate DID gain weight! Pray for another good gain next week! (oh- I don't know if I mentioned last week that she had an ear infection, but it's gone, so that's NOT the cause of the sleepless nights/fussy days).
