The short answer
Among the 119 Actually Sleeping video reviews that name a timeline, 46 families describe their baby sleeping through on the first night, 81 within three nights, 115 within seven nights and 119 within fourteen.
Nights until sleeping through

| Newborn to 3 months | 19 | 12 |
| 4 to 6 months | 26 | 18 |
| 7 to 9 months | 33 | 18 |
| 10 to 12 months | 27 | 15 |
| 12 months and older | 25 | 18 |
How these numbers are counted
Each video review on actuallysleeping.com carries the result the family names, such as "Night 1", "5 Days" or "1 Week". We converted those to a number of nights. Reviews that describe a result without a count, such as "Since Birth" or a bedtime-to-wake-up time, are left out of the timeline figures but kept on the site.
"A few nights" and "a couple of nights" are counted as three. "3–4 days" is counted as four. Day counts are treated as nights.
What these numbers can and can't tell you
They describe what families chose to say on camera after the program. They are not a clinical study, they do not include families who didn't record a review, and they say nothing about how a specific baby will respond. The 14-day guarantee is the company's own commitment for a family that follows the plan.
