She is loving Lucas' new carseat, lol!! She can inherit it in a couple years...Even though she just turned 1, she'll be rear-facing until she reaches 35lbs, the highest weight of her convertible seat, as is recommended by the AAP (American Academy of Pediatrics) "it is best for her to ride rear-facing to the highest weight or height allowed by the manufacturer of her car safety seat."
Here are a couple of videos that show why it's so important to keep a child rear-facing as long as possible. The 20lbs and 1yr. guideline is just the bare-minimum required by law...I'd prefer Abby's spine to stay in 1 piece if God-forbid we were in a bad crash. (just click the text)
