Aiden can sort of sign “airplane.” We live near a small airport and directly between (by many miles) two major airports, so we see and hear planes and helicopters at all hours of the day and night. Since the weather has been nice we have had the windows open and I noticed Aiden perking up every time he heard one fly over. I have also noticed that he can see them sometimes from our kitchen window during feedings. I have been trying to sign airplane whenever he notices and apparently he has noticed me doing so.
He can’t quite do the sign completely correct, as you need to bend your middle and ring fingers toward your palm and “fly” your hand above your head like an airplane. He takes his whole hand and “flies” it over his head – close enough for me! It is too cute because he is so proud of himself when he does it, not to mention I make a big fuss whenever he signs anything.
He now signs it when we take walks and he sees/hears one and also if he only hears the sound. When I point out a picture of a plane in a book and do the sign he immediately gets up and goes over to his window to try and find it in the sky. I mean, come on, how cute is that?!? I can’t say it enough times, but he never ceases to amaze me.
