When is snack/lunch time?

[Yarnlover]

Our am snack is at 9:00 or 9:30, lunch at noon, and pm snack about 3:00.

Here's a question, I posted in another thread about my daughter scratching another child during free play when a toy was grabbed out of her hand. To other ppl use free play time to get meals ready or do most of you do this in advance? My kids are all between 18 mo and 2.5 years, I feel like if I am not right to them every second there is always a chance someone is going to pinch, grab, push, another one.
