I find that 9 times out of 10 my daycare kids nap better on Mondays. They can be a bit overtired, tearful or grumpy, but a good routine and predictability tend to do the trick and if push comes to shove, I just serve lunch a little early and they take an earlier nap. Very rarely do they wake up earlier than their usual time either so Mondays can end up being a great day here, unless we actually want to get anything achieved that is. Snacks, Lunch and naptime are kept regimented, but otherwise Mondays tend to be a free play kind of day and it seems to work best for all.
