I need to choose between these options for 6mo DS for an upcoming plane/car trip. DS is a very small 6 months at 14 pounds. We don't have a plane ticket for him so any seat we take will be checked/gate checked for the flight. Should we:
1. Take the snugride (without the base)? DH is confident with install with the locking clip and no base.
2. Take the sngride and buy a base there? We will not be spending much time in a car other than the ride from the airport to nana's house.
3. Take our Cosco Scenera? It seems like a big seat for such a little guy, but I like that we don't need to worry about the base issue.
4 yo DD will have a CARES on the flight and Nana has a 5 pt harness seat that I believe is FF only- so not an option for DS.
