It's been nearly 3 weeks since we started operation bedtime and the light is visible. Plan A was not too much of a success in terms of bedtime, but what it did achieve was a daytime routine almost instantaneously. She went smoothly from 6ish feeds a day to 5, 4 hourly between 7:30am and 7:30pm plus one overnight.
She got a bit sick the second week which confused the whole thing. I tried a few other bits and bobs without much success. Then Tuesday this week, I tried "let her cry". Just a standard controlled crying technique, letting her cry for between a couple of minutes and 10 minutes and then reinserting the dummy, and maybe some other comforting if it seems sensible. This was a great success. She goes to sleep on her back, no rolling over. The time to total sleep is still a little random, but the average is much less.
And then the really amazing thing happened. She has started sleeping through! 3 nights out of 4 up to today. 4 feeds total in a day. I don't suppose I am free of night feeds entirely yet, but it is clearly on its way.
Something truly magical happens when 3 months of age and routines collide. And all this good stuff started from the simple act of fixing the last feed of the day at 7:30pm. It's all good.
