Anyone tried to take their little ones dummy away? If so how long did it take before they were ok going to bed? We've just done the 'dummy fairy' with our DD (2 1/2). Currently on night two of screaming the place down. She only ever had it for sleep but is finding it really hard! As am I! Tempted to give it back but the dentist said was effecting her teeth so want to be strong. Any advice gratefully received!
