LO just turned 5 months old last week. Up until this point, she was waking up an average of 8 times a night. We had tried letting her CIO in the past but we just didn't have the heart to let her cry for more than 2 minutes. We finally decided to give it a fair try, and we had success! It took us 1 week to accomplish going from 8 wake ups, to 1-2 wake ups. Here is a our nights looked like:

Night 1:
7:00pm- Bed time
9:42pm-10:14pm CIO 32 minutes
11:09pm-11:14pm CIO 5 minutes
1:00am- Nurse
3:00am-3:26am CIO 26 minutes
4:30am-4:46- CIO 16 minutes
5:30am- nurse
5:50-5:55- CIO about 5 minutes
8:45- up for the day
Total CIO time: 89 minutes

Night 2: We decided to adjust her bedtime
6:30pm- Bedtime
12:45am- Nurse
5:45am-Nurse
8:30am- up for the day
She had no CIO sessions tonight

Night 3
6:30pm Bedtime
7:48pm-8:08pm CIO 20 minutes
8:24pm-8:40pm CIO 16 minutes
9:15-9:26 CIO 11 minutes
2:45am Nurse
6:10am Nurse
9:30am- Up for the day
Total CIO time 47 minutes

Night 4:
6:30pm- Bedtime
12:30am- Nurse
6:10am-Nurse
8:20am- Up for the day
No CIO sessions

Night 5:
6:30pm Bedtime
12:45pm Nurse
5:00am Nurse
8:45am Up for the day
No CIO sessions

Night 6:
6:30pm Bedtime
11:50 Nurse
5:40am Nurse
9:00am Up for day
No CIO sessions

Night 7:
6:30pm Bedtime
3:50am Nurse
5:00am I needed her to nurse a little on the other side, since I was so full from her sleeping so long. This took less than 5 minutes.
8:40am-up for the day
No CIO sessions, this was our best night yet with a stretch of over 9 hours.

I'm hoping this trend continues, at her age, 1-2 wake ups is fine by me. I am so glad we gave CIO a chance, we are all getting so much more sleep. LO is much happier and so is mommy and daddy
