Curious Mind

I am a mum of a 9-month baby boy Shuen, and a self-confessed data junckie, who is obsessed on data collection and crunching. As I was getting close to the return-to-work date, so was I being increasingly anxious that my baby boy still couldn’t sleep through by 7 months. This means that I won’t have my beauty, or rather, sanity-sleep that I have been longing for since late pregnancy.

My hubby and I are not believers of crying-it-out (CIO) sleep training method. So, we are determined to try everything we can to fix this before resorting to CIO training. We started with ruling out the common reasons that were brought to our attention: feeding the baby nice and full during the day; controlling the room temperature; no nappy-changing during the night etc, etc… But Shuen just didn’t sleep through, well, regularly I mean.

Some has suggested that we shouldn’t allow baby sleeping too much during the day. And others suggested baby shouldn’t be allowed a nap after 4pm, otherwise, they don’t sleep through the night. What puzzles me most were whether the length of day naps and timing of the last nap do take their tolls in Shuen’s case, as babies are so different. Afterall, things affect one baby might not affect another.

If fact, it’s not hard to answer these questions with a simple linear regression and correlation analysis. So, determined to  get my beauty/sanity sleep back, I set out to note down length and timing for Shuen’s night sleep and day naps in 24 hours on a daily basis over a period of 41 days (*small base, caution!).

And here is my conclusion:

1. Shuen has slept-through only 37% of all 41 nights in this research period. Better than I thought, but not good enough.

2. With R-square of 0.12, there is obviously no correlation between the length of Shuen’s day nap and night sleep quality.

3. The table below shows that sleep-through rate is 4 percentage points higher on the days with late naps* than the days without. Evidently, Shuen’s late day naps also have no impact on whether he sleeps through or not.

As you probably guessed, CIO (cry-it-out) sleep-training started as a result of this analysis. This is what you call actionable research, by the way.:) And yes, this is what happens when your mother is a data junkie, a proud one though.

In terms of what people care about keeping private online, I am surprised that only half of the people mentioned ‘internet browsing history’. This means, half of the people don’t care keeping it private at all.
