Self-weaning or Nursing Strike?

I have a baby question.

Kaitlyn has been less and less interested in her bottles lately. If I am home, she will nurse off the boobs for about 10 minutes, then drinks 30 to 120mls (mostly closer to the 30mls) of bottle. But most of thetime, it seems that she just wants to push the bottle away It makes me feel like I was force feeding her, and she's getting upset at the sight of the bottle. When I am not home, she still wouldn't take more than 50mls each feed, that means she only gets150mls from 6am to 7pm!!! According to all the baby books and stuff, she should be eating 210mls for EACH MEAL. I try to squeeze in an early morning boob feed and try to get her to eat for as long as possible (she's normally half asleep and can be "made" to keep sucking) and I feed her before she goes to bed. I doubt I have much milk by the end of the day though.

Anyways, She loves her solids and will eat 80mls to 100mls of solids 3 times a day (morning and lunch, 2 cubesof avocado, 1 cube of fruit, some fomula to thin it a bit and 2 scoops of rice cereal. at dinner, mum makes rice and chicken congee for her and she will eat 100 to 150mls of it).

She put on 300gms inthe week after we came back from Tresillian (but that's after she'slost 300gms while we were there), and she has not put on ANYTHING now for 3 whole weeks! She's falling off the growth chart... down to 10% now... my poor baby.

She doesn't seem hungry or upset or sick at all and is producing plenty of wet and dirty nappies. I am just worried that she's not eating enough milk...

Is she self-weaning already? or she is on a nursing strike? I am not sure how to get her to put on some more weight... /sighs.

Any ideas?
