Re: Baby suddenly not gaining
Here's the link the PP was talking about (I think): http://kellymom.com/health/growth/growthcharts/
Definitely normal for the rate of growth to decline as time goes on and the baby starts putting more calories into action (reached, rolling, kicking, crawling, etc.) instead of packing them on as fat.
Since diaper output is on track and the baby is a nice weight for a 6 month old (which is what she is, no matter how long she's spent on the outside), I would feel comfortable waiting quite a bit longer before starting to freak out. Her intake at daycare is low, for sure. But since you're encouraging reverse cycling, it's very possible that you're making up for it at night.
Coolest thing my big girl said recently: "How can you tell the world is moving when you are standing on it?"
