Thanks for all the replies.

Barb - i love you, you're so helpful! TY for the nice words . I was looking at photos of her when she was about 2 months old and she's definately not as fat as she was, though she's still got lovely big rolls on her arms and legs! The main thing I noticed was that when she's lying down and doesn't have a full tummy, I can see a little bit of her rib cage protruding when she breathes. Is that normal? I haven't been *too* concerned seeing as how she seems perfectly healthy in every other way. Perhaps her colic contributed to her weight loss? Me and my partner both have big builds naturally.

mbear - She's been able to support her head for quite a while now, at least a month. Though I don't know if that means she's physically ready for solids or not.

I'm going to make an appointment with the child health nurse, I tried to before I just never get in in time. Hopefully she'll come to my house because I have no transport right now. I took Aurelia to a GP a few days ago because of her colic (which has finally gone away - YAY!) and he said she healthy (though he didn't weigh her).
