Some people just don't get that this is how we make our living!

[5 Little Monkeys]

I don't have a late payment fee. If you are late 2x with payment though, you will be asked to find other care. I have never had anyone pay late. I now ask for it in the morning though because I did have some parents who would have to run home or to the bank before picking up their child and it was making my days longer. As long as it is paid on payday, I don't mark it as late.

If you prefer to have a late payment fee, I would increase it for sure. $5/day isn't a big enough incentive for some. You could also ask if she would prefer to leave post dated cheques with you.
