Someone needs to make a car seat that, #1 won't cut into a child's neck or legs. (Because I'm sick of hearing how "dangerous" belt straps covers/protectors are from people) #2 will have a car seat cover to protect the car from any spills or sicknesses that happen (because having a new car and then a sick child is horrible especially when needing to clean the car) #3 will actually strap into the car with more than just the 2 little straps it gives and the seat belt (I hate that if my car flips, it's like her seat will fly up and down in the air---AND YES it is put in correctly. I had the instructions as well as the fire department put it in since I travel 3hr or longer at times with her since she was born.) Lastly #4 A car seat that would almost crandell the baby. By that I mean it would be nice if the sides and head and feet would be higher above the child. Almost like putting the child into a protective eggshell that will hold the child safely if the car was to rollover or any type of wreck!
