My son is 4.5 and we are driving to Florida this summer so I called Debbie to come have a look at our car seats. We discovered our seats were not installed properly. She spent hours with us showing us all the tips and tricks of the Diono. I was incredibly impressed with all of her knowledge, time and patience. I wish I would have called Debbie when my son was born years ago. I highly recommend her to anyone with a car seat!!!
