my one biggest pet peeve is that my parents don't really think that car seats are that important. they grew up in egypt, where no one really uses them, and very few people own cars anyway. but they quite often allow kids to ride in the car without a booster seat, and most of their friends are the same way. I got yelled at the other day by my mom's friends because I refused to let my 5 year old brother in the car without a booster seat. she said there wasn't enough room. she drives a minivan that seats 7 and there were 6 people in the car. and she said we would take too long. it was one of those little ones without a back. you just sit them on it and buckle them in, it isn't like its a huge hassle like the infant and toddler car seats! and no matter how many articles I show them about how car seats can save a child in a crash, and how a seatbelt is meant for a fully grown adult and won't help a 5 year old, they never think to go grab the carseat. I am the only one who thinks of it.
