I recently cut DS down from 4 feeds to 1. I basically said that 'boo' is only for dawn and if he asks for it tell him he has to wait and try and distract him. He has mostly been ok, a whinge for a minute or two but fairly easily distracted. He was getting sick in the last week and so did feed a couple of times over night but now that he seems to be ok I will be cutting him back again.
