Ok well on the VIC health growth charts for her age and weight (based on 7kg) she is just a bit over the 97% percentile. But that doesnt not mean she is fat or your overfeeding.
If you want to have a look (im sure WA would have something similar) go to:

I done a rough work sheet for Jasmine....and i just entered you figures...

At 180 ml, 6 bottles, 7.5kg it reckons your bub should be having 225ml each feed....so thats alot more then what she is having..LOL

I wouldnt be to worried....she will loose the chubbiness...once she gets active (and crawling) you will notice a difference.

DD1 has always been under average and a petite little thing....DD2 isnt chubby but is more chubbier then her sister.
