I had a peron who was looking to be licensed tell me she wouldn't take babies because she couldn't see taking them outside! I take a pack and play out plop it in the shade and cover the top from bugs and they are just fine!
We always take a walk and then play outside as much as possible. I have a great patio space and we often spend a good chunk of the day out there. So happy it is cooling down some! I love fall.
