Astrid, my 1 yr old was doing the whole hand shoved down the top and yelling 'boob' at the top of this voice thing...... But we managed to stop it by telling him 'that's not the way to ask for milk' (I never say Boob, don't know where he picked it up from ), then showing him to gently tap my chest. After a couple of weeks he didn't need reminding any more. If you're not happy with the chest pats, maybe another action would work just as well? Good luck finding something that works.

Oh and the wriggling? Haven't been able to stop that. If we're lying down he'll usually end up doing headstands, or if we're sitting, he'll wriggle till his feet are on the floor.......all fun for now!
