we have had the odd occasions with sleep including this past fortnight, we have resorted to control crying and yes it's hard but its worked!! what we do is go in after3 minutes of real crying not whinging, put our hand on her, no talking no eye contact, count to ten in our head then walk out, yes she gets hysterical when we leave... go back after 4 minutes repeat, then 5,6,7, cos sophie is older we do 3,5,7 minutes, this is on the advise of MIL who works in a parne and baby unit, it takes 3 days and 3 nights but it gets easier,
