Ohhh Bek. I'm sorry to hear you're having issues with Miss E sleeping. I TRULY understand how hard it is.

How long has this been going on? I remember at one point she was doing 5 hour blocks during the day?! Is she able to self settle or are you doing other things to get her to sleep initially?

Around the 4 month mark lots of babies have a period of sleep regression - do you think this could be the case?

It sounds to me like you're doing all the right things and as much as it sucks, this might just be a 'ride it out' situation.

really hope things improve soon.
