Hey Mel,

Aidyn used to do the EXACT same thing... at pretty much the exact same age too.
It perfectly normal, but yeah, its very much an attention seeking behaviour.
It went on for quite a few months with him, and he still does it now oaccasionally. I guess he knows that we will always come running. Sometimes its just the gagging, but other time he will make himself full on spew.
I think the best thing to do is to either completely ignore the behaviour, or give her a stern 'no' and pull her hand outs (although I've found that usually sets them off laughing, lol :roll: )
