We have to fly at least every 3 months with our son (J), now 2.5, for medical reasons (he has rare eye condition), so I have an unusual amount of toddler flight experience. My son has been able to get the seatbelt off since his first flight as a non-lap child. We have CARES which keeps him from taking the seat belt off, but it sometimes slinks down on the seat and loosens. Also he sometimes still wants to sit in my lap during take off and landing which is aloud.
If your interested the routine that works for us is as follows:
we fly southwest and I always load with family boarding between A group and B, because we still get a great seat but have less time on a nonmoving plane.
Find window seat for J
Let j move around freely in seat as long as possible
When necessary give J choice between cares seatbelt or my lap
The time on the Tarmac before take off is the trickiest, I always have a sucker at the ready and pull it out just when J gets fussy
Once we are in he air and the seat belt sign is off I let him return to his seat if in my lap or if in seat, I loosen th belt to give him more movement. At this time I start his movie on the iPad and pull out the crayons etc.
Landing is the next tricky part, but we do the same, and I have spare sucker. He sometimes crys right at the descent darts (ears), but suckers, songs, and nursery rhymes help.
Probably more info tan you bargained for, but I thought I would share
should I
myself?
