What to know about Tommee Tippee Groclock 499051

A star-and-sun sleep trainer. At bedtime a blue face shows a sleepy owl surrounded by stars; the stars fade overnight to show time passing, and a yellow owl face appears at wake time. It has two wake-time settings (weekday/weekend/nap), a display you can dim or switch off, an optional alarm, and comes with a bedtime storybook. Best for teaching the concept of time.
Editorial notes

Why it stands out

Why we like it

Groclock is the only pick that shows the passage of the night with fading stars. For a child who keeps asking whether it is morning yet, that visual countdown answers the question without a parent.

It has two wake-time settings for weekday, weekend and nap, a display that dims or switches off, an optional alarm and a bedtime storybook. It is sold and shipped by Amazon at a budget price.

What to know

Skip it if you want sleep sounds or easy programming. Evidence comes from two sources, Lucie's List and Fatherly.
