You can't leave a 3 year old alone for a long period of time. They are almost worse than 1 year olds. They'll go into the medicine cabinet or, if that's all locked up, the fridge. They know how to create havoc. They get outdoors without you knowing about it, etc. You have to watch them like a hawk.I was thinking that it could be that she let some aspects of housekeeping go when the kids were younger and really needed more time and attention, and now that they're older and able to play on their own for periods of time, she's still stuck in that old way.
I had more time when my child was bewteen the ages of 0-2. They sleep more. Then when they're about 4 they're better. Then, they hit the teen years and all hell breaks loose.:)
