How can I teach my 7mth old dd2 to get herself to sleep? She only goes off either in the car (occasionally the buggy) or while bf, but even bf doesn't work half the time so she's awake for a couple of hours in the night - we've tried leaving her, going in every few mins, rocking her, bringing her into bed with us - nothing works - she just eventually gives in after 2-3 hrs. Only has naps during the day by going off in the car. Have tried putting her down at regular times when she seems sleepy - worked for week or so but now back to screaming if you leave her - and screaming even louder if you go in and try to soothe her! Help!
