Question: how do you know it's time to transition from 3 to 2 naps.And how did you do that? Cold turkey or 15 minutes increments added to wake time, if so what happens with bed time?

Why I even thought about it:

It takes my LO to fall asleep for 40-50 minutes now instead of 5-10🤦‍♀️ ( feeding and after she's full anx turns her head other side rocking her to sleep and put into crib, won't consider sleep training, as when she cries for long time she stops breathing😖) and likes to wake up in the middle of the night to party🙄Heeelp😴👶
