I just don't know what to do 
My 20 week old is sleeping worse than ever. 30 min naps (unless on me) during the day 90min to 2 hour awake time between.
Will not self settle at night - she screams - used to be ok. Either feeds to sleep or needs to be rocked. Does a 3 to 4 hour stint and is then waking every hour or so 
I'm so tired I'm getting ratty with my older DC and I just seem to spend all my time trying and failing to get her to sleep properly!
Anyone else dealing with this - I feel really alone, all my friends babies sleep well.
My older DC was exactly the same and it's taken years for him to sleep properly. I feel like such a failure
