Hollye, FAR OUT, I didn't realise Mia vomited that much everyday. You poor things! You've probably already shopped by now, but here are some things Peter likes that you could try:
- avacado on cruskits (broken into about 4 bits)
- butter on toast or bread
- those mini rice cakes with a little bit of dip on them (or plain)
- ham (he likes to suck on it)
- arrowroot biscuits- if you don't mind giving her sweet!

Hope the solids help!!!
