My 20 week old is currently unable to link sleep cycles at all really, despite being able to self settle (not always but often) at the start of naps and bedtime. This means she is waking 45 mins after every nap, and 2 hourly at the start of the night, and 1 hourly after 3am.
What actually helped yours in the end?
Just giving it time?
Wake to sleep?
Resettling each cycle?
Crying it out? :S
We are all suffering from not enough sleep so feeling quite desperate
