L's first three meals were:
1. carrot puree
2. butternut squash puree
3. sweet potato puree
She loved them all

and her poops turned bright orange!
I generally followed Annabel Karmel's suggestions for good first foods, added new ones quite quickly (as L didn't get any bad reactions) and combined them/mixed them up lots too. Didn't do rice but gave L baby porridge for breakfast after around a month I think.
Have fun!
