Is she still having milk? If breastfed, I wouldn't worry too much about what she eats so long as there's some extra iron, zinc and calcium. If formula, would look at cutting back as much as possible.

The mess is also normal. That's not going to change any time soon, I'm afraid.
She only has sippy cups of water or cows milk and sometimes fresh sqeezed orange juice. We stopped formula a few months ago. And it's always just a half cup because she never drinks it all anyway. Bummer about the mess, I feel like a bloody maid lol

Exactly what onthefly said.
It takes 2 to have a battle.
Only offer her healthy food. She will eat it if she's hungry. If she doesn't want to, that's her choice too, and that's ok.
Kids are messier eaters, you just have to get used to that. Food is fun to squish and throw.
That's the problem Heaven, I am offering healthy food and she wont eat it. I am not comfortable with her just eating yoghurt. I do buy a good brand, but still it's all dairy she's eating. No vegetables or meat. pretty much anything that isn't sweet she won't eat
