we are planning a road trip next month and our LO will be 7 months at the time. she is currently still using her infant carseat (graco snugride) she only weighs about 15lbs although she is tall. I'm not sure if we should make the trip in this carseat or if she will be more comfortable in a convertible car seat. The convertible will force her to sit more upright so I'm not sure if she will like that for the whole 12 hour drive. What would you do?
