we went camping and my bil didnt want his son (3yo) to have a bottle anymore, but his wife kept giving him a bottle.. so we taught him that after he finishes his big m to throw it in the fire, we gave him big m in his bottle then he threw it in the fire, didnt even blink an eye or want it after!

my other nephew went through a clean freak stage so we told him his bottle & dummy was dirty and he threw it in the bin.. lol..
