Hi, I have felt your pain. Am on anti deps due to the sleep deprivation and anxiety over my DDs sleep. She is 9 months old and had never slept throught the night. She would wake every 2 hrs after 11pm.
I did controlled crying 10 days ago.
Started on a Friday night so DP could do it with me. I never thought I would be strong enough to do it but I did.
Here is what we did:
I give DD the bottle in my arms in the nursery with only the nightlight on. Nice cuddle and whisper sleepy time soon and do a shocking rendition of twinkle twinkle little star!!
I put her down and stroke her hair and say sleepy time and give her a kiss.
DD is very sucky (had a dummy before leaving hosp, on midwife's advice)
I give her the dummy and it falls out when crying but have 3 in there on dummy clips for her to find.
We went in every 5 mins..10 mins max if she was quieting down. She did get a little worked up again but got better very quick. Every single time DP and I say "SHH SHH Sleepytime"
Just be prepared in case she is sick. DD was on the first two nights.
I changed her and the bed and just started again.
1st night cried for an hour every wake up. Get lots of coffee/mags/tv in bed whatever. You maybe shattered next day too. So may she.
2nd night similar but not quite as bad.
By 4th night was 20 mins and less wake ups.
By 7th night, no crying when put down.
When she wakes she just whimpers and goes back to sleep.
Keep a diary and record how many times went in and times she wakes and falls asleep. This way you can see your progress
Just remember she will give it her best shot ato get you to settle her. Stick with it and keep the end goal in sight.
Although the first 2 nights were awful, the end result is you and DD will be better off.
I nevr thought I would be the type of person to do CC but it was my last resort and now I am glad we did it.
Hope this is useful. Sorry for long post!
