Hi Rosy,
My DD - also Chloe! is also 22 months and what you have written in your post is exactly what happens in our house!!!!! Even the making herself sick bit!
Unfortunately I haven't found the solution yet.
But you are not alone. Distraction sometimes works, but today she managed to help herself to the milk carton in the fridge, so I guess a safety lock for the fridge door is needed now. DD did have a bit of a cold during the week, which led to more milk requests, but b/c she usually only has milk or water, I tried to offer her juice as an alternative to milk to keep her fluids up and that seemed to work for a bit.

I'll look forward to seeing some responses too
