Hi! I am back again requesting some help to find a good infant seat for our baby girl on the way. However, since this is our third and we're pretty much broke, I have some requirements. My babies are big so I need one with a decent weight limit, preferably 30+ weight and height limit. I also really need an inexpensive seat since my my babies grow out of the infant seats rather quickly. We have a town and country minivan so something with an easy install would be great! Thanks!
