At what age was your LO when you switched from using an infant car seat to a convertible car seat? Did you follow the height and weight restrictions and keep them in the infant seat for as long as possible?

Right now LO is still in the range and she is 7.5 months old. It's freezing cold here, and I'm hoping she stays in the range at least till spring! It's so easier having her buckled in the house, and carrying the seat with her in it to the car! But I have a feeling she's going to hit the height limit soon....
