I'm not sure I understand exactly what you mean
I did this:
DS woke and mantra cried, I left him
DS' cry escalated to 'I need you', I went and soothed him and once calm, left.
Often he would go to sleep, but if he cried again, I went in and soothed again.
Do you know why your LO is waking? OT/UT/discomfort/hunger? What's your EASY at the moment?
