So, left alone with 3 kids, what did I do? I ran home to my Mom of course!
I took the 3 kids to spend the night and had a great time with Mom. The baby was kept happy exploring new things and places. The kids get to play on her computer.
Here's a picture of her in the morning, biting on to her sippy cup and crawling on all fours. Mom was laughing at the tiny "puppy" crawling about.
