i have no idea how to set it up but I want a real car seat for maggie soooooo bad. hubby just won't let me spend the money on one so i guess I have to try and make one. Right now I have maggie's "dogo" harness strapped into the cars seat belt to keep her "safe". I would love to get her a car seat that would help her sit higher so she can see out. 
 
If anyone has any ideas as to how to make a car seat, I would love to hear it 
 
 
good luck setting the seat up. I am sure your baby will LOVE IT!!!!!!
