Hiyah,
Happy to share info. DS is at a Leapfrog. They're a chain, so I suppose it depends on the individual management, but the staff are just lovely. DS is in first steps ( 12 - 18 months) and I get a report sheet everyday detailing:
Activities - Singing, sand play, puzzles etc
Nappies - What times and what type (soiled or wet)
Food - e.g. Breakfast and how much they've eaten (All - Most - Some - A Little - None - Second helping)
Drink - What, when and how much ( as above)
Sleep - When and for how long
I think that's it... they also note if he has had any accidents, been given any medicine (which you have to sign in anyway) or they're running out of anything.
I think it's just as important to know how much they've drunk, as how much they've eaten. Do the nursery only use the filled beaker you supply? If yes, then I suppose it's pretty easy to know what your what your DD has drunk. If not, then if this is the second time they've forgotten her milk, I don't think it would be unfair to ask them to note this for you.
If you want to know anything else just give me a shout.
