Just starting out the Ferber method.

At 10 minute intervals of letting her CIO before attempting to soothe her while she’s still in the crib. Is there a certain amount of times you’ll do this consecutively before picking baby up? I hate hearing her be upset but I do believe in sleep training as it did wonders for our first in a very short amount of time. Any advice or insight is appreciated👍

2.5/3/4 is her average day.
