My LO is nearly 6months old and she is on a 3hr EASY cycle.
We have recently increased her awake time from 1h45 to 2hrs.
When we did this, her naps decreased from 1h30 to 1hr and she became a lot more difficult to settle for her day naps.
She has no issues getting to sleep at night time and sleeps right through with no feeds or awakenings.
I was hoping to start extending her EASY cycle to 3.5hrs, but this is not going to happen with her naps shortening!
