It is so HOT outside! I had a Mom complain that her baby cried every time she put him in the car seat - when we went to look at it I realized the car seat and car we super hot. I would cry too!
Here are a few simple tips:
Try to park in the shade and leave your windows cracked open when ever possible.
If you have an infant carrier car seat, take it inside the air conditioning with you.
Try to always open the doors and windows and air out the car before getting in.
Run the AC for a few minutes and cool off the car before you put the baby in the car seat.
Take a reusable filled with frozen ice packs with you when you go out and leave it in the car seat when you are parked to keep the seat cooler.
