I exersize Rambo by hold him with and up and down motion while he is facing the sofa. The up and down he will flap then take off and land on a soft sofa.
So I actually started doing something like this the past two days. In the morning Luna has decided that all she wants to do is perch on Michael's shoulder while he's still in bed, regardless of whatever I'm doing. (She has decided the past two weeks that he is suddenly her absolute favorite). So I've been trying to hold her in front of the bed, and dropping my hand suddenly to get her to fly off. It works most of the time, and we do it a couple times for good measure. Yesterday she landed really gracefully for the first time.
I have high hopes.
don't know how long it will take her to figure out that she can fly on her own.. wondering how much time we have left before we have to supervise her a lot more closely.
