A.K.
Ups and downs are toatally normal. At your next appointment ask your doc specifically if you should be concerned. My doctor told us at out last appointment that normal growth for babies is rapid the first year (doubleing or even tripleing in weight) but the second year he doesn't expect that my daughter will put on more than 4 pounds (she's around 70th percentile now was 90th at birth.)
As for the feeding thing. Is she interested in self feeding? My daughter won't hardly eat at all if it's on a spoon. She's very determined and wants to do things for herself. So she gets little bits of food that she can feed herself and this way she eats pretty well. Also you're daughter is a year old now (as is mine)so you can be more adventerous in what she trys. My daughter really responds to foods with real flavor. Instead of steeming her vegatables I've started roasting them. Now she loves her broccoli so much that I've had to start buying giant bags of it at costco. She also like onion, garlic, termeric and cumin. I have a great recipe for indian lentals at home (I'm at work right now - being extra productive;-) My daughter loves these lentals so now we have them about once a week (they go really great with salmon which she also likes.) If you'd like the recipe send me a PM and I'll send it to you as soon as I get a chance (things are crazy at home with halloween.)
