Convertible car seat 🗣

I just purchased a convertible seat because my chunky boy was so uncomfortable in his infant seat and really didn't like car rides. The seat was also getting way too heavy for me. I have yet to try it out but I'm pretty excited.😁 I'm just curious for those who use this already, how do you transport baby ..
1) Just carry baby
2) Stroller
3) Carrier
4) Other(explain)
