I'm a stay at home mom AND I work from home so I'm with Chewy A LOT. I leave him home when I pick my son up from school and if we go to the park, he may be at home alone for about 3 hours. The rest of the day I'm with him.
On the weekends it's a little different. He'll be home alone for longer periods of time although depending on what we are doing, he'll sometimes come.
