Hi. I have a 2 1/2 year old who is 30 pounds and 37 inches tall. What would be the best booster seat for her? She is in a Britax RA now, but I am planning to move my 5 1/2 month old into that seat. Do you think it would be safer to use a booster seat that comes with the 5-point harness or would it be just as safe with the seat belt option (i.e. Britax Starriser/Comfy)? And which booster seat have you found that works well for the sleeping toddler? We travel a good bit for long distances.

Thank you,

JBJ
