Thanks for all of the replies my son is 2.5 and he is about 25lbs, but he does not like being restrained we never had this problem with my other 2 children. Last Nov we went to Disney and he wouldn't sit in his seat ( we didn't bring the car seat since he was a lap baby at the time.) He wouldn't sit on our laps so he ran around the plane it was a nightmare

so this time we are bringing the car seat but when I saw this thing I thought maybe this will work and he can't get out of it. Once he is in his car seat he calms down because he knows there is no winning and he falls asleep. What would you do stick with the car seat or go for this gadget?
