If you have kids, make sure NOT to put bulky coats or jackets on under their car seat straps. If you get into a car accident, the coats will compress and make their straps too loose, which can have tragic results. Babies can be buckled up inside the house and covered with blankets, then carried out to the car already in their seats. Toddlers can take off their coats for a few seconds while buckling up, then put the coat back on backwards unzipped. If you have to loosen the car seat straps at all to accommodate the coat, it's too thick to go under the car seat straps safely. Lots of folks from warmer climates were never taught this because it wasn't relevant to them, so I figured I would share just in case!
