We've upgraded to the big boy seat. It's the Graco Extend2Fit and Rein loves it. (As do I). He was so uncomfortable in his infant carrier no matter what we did. And honestly we've stopped carrying the seat for awhile (He's 23 lbs and just turned 7 months Monday 😩😭)
And I kept it more out of convenience if we were out we could carry him in it. But since he can sit up we just put him in his stroller or I just wear him. @cass3boys
I'm with ya I usually leave my sons seat in the car unless I'm leaving him with family and he's about to be 8mos and is the height on a one year old almost
