Just a further note, for the benefit of others,
we spent all last week trying to put DD on the 4 hour Baby Whisperer routine, and it didn't really work out. She ended up overtired & cranky & refusing to feed as a result, so am now going back to a more gentle amble towards that routine (if she even ends up there).

Our main aim now is to extend daytime sleeps and to get rid of the dummy (gently if possible).

Am trying to regain some confidence in hoping I know DD better than the books, but it's been a hard couple of weeks.
