2boyz.. usually when I do the wrist thing it will go through all of your kids, even current ones. mine goes side to side for a girl, and up and down for a boy (my sister in law, who also has really good accuaracy with this goes in oppsite direction of mine.) So, if you have two boys right now and it went side to side first, i would think side to side (then a slight pause maybe or a circle for me means 'thinking') then another side to side, pause or circle then whatever else it has to say.
That's how it works for me anyway.
When I hold mine over my wrist it swings side to side, pause, up and down, pause, up and down, pause side to side, pause, up and down.. and when it's finished it will sit there and do a little quiver! PHEW -so yeah, it says 5 kids for me!!! GIRL, BOY, BOY, GIRL, BOY
