Thank you Kate, that was very helpful.
EASY worked so well for my first two children that I am keen to implement it again, but I think maybe its a little early, possibly for the reason you mentioned about babies being unsettled until 3 months old.
For example today she napped for nearly 3 hours, then cried for food so I fed her and then she went to sleep straight away for another half an hour, so we had A after that.
As for being held, when she is very tired she gets very fed up if being held and only calms down if you put her in the crib or chair. I think I need to try to implement a routine slowly as its a bit all over the place at the moment.
