Installing spare car seats in our second car (VW Atlas) after vacation! Installing car seats is not my FAVORITE thing to do, but it’s SO important to have your car seats correctly installed. A reminder: the more expensive the car seat does NOT equal more safe. All car seats must undergo the same testing to be on the market. Safety with car seats is ALL about correct installation and use of the car seat such as correct weight and height limitations and correct harnessing. Questions about install or correct use? We can help through a car seat consult!
