Well after my last post and all the worrying, yesterday Ella ate her dinner! It was sweet potato, and following the advice on here I mixed it up really thin and mixed the baby rice in with it. I didn't expect her to eat anything, but she gobbled it all down like a little bird.
I was so pleased, I left the empty bowl out to show my husband when he got home!
Who knows why it worked, maybe it was a combination of me being less stressed about it, making the food thinner, and Ella being in a good mood.
She didn't eat much breakfast but ate a bit of lunch. I'm just going to carry on really slowly and not force it and see what happens.
In the UK the recommended age to start solids is 6 months, because of the baby needing iron, but a friend told me that in America the recommended age is now 8 months - is that true do you know?
Anyway thanks everyone, and thanks to Geoffrey's mum for starting the thread, I hope you are having more luck getting Geoffrey to eat.
