Yep,...totally normal glider behavior.
They totally remind me of a 2 yr. old at the play park.... try slowing a toddler down long enough to get kisses in when all they want to do is get to the fun toys with all the other kids.
When mine jump on me during playtime I'll bring them up to my face and smooch, smooch, smooch as fast as I can with them squirming the whole time! I can just hear 'em.... OK MOM, THAT'S ENOUGH, LET ME GO SO I CAN SEE WHAT COOL THING AERWEN JUST FOUND!!!! And the second I release them they're off and running.
I just chuckle and wait til they make the mistake of coming withing lip shot again.
