Choosing & Using a Sleep Trainer Clock

Children waking too early in the morning is a problem for the whole family. When children don’t get enough sleep overnight, they will be grumpy during the day. And when parents get woken up too is harder to cope with grizzly children! Unless you take action to teach your children to sleep in later in the morning, this vicious cycle can become a very firm habit.

Reasons for early waking & what to do about it:

How does a sleep trainer clock help?

Children don't know that time it is...they can’t tell the time from a regular clock and their body clock could be telling them it's morning at 5am!

A sleep trainer clock uses a simple visual change to show when it is ‘morning’ and therefore when your child is allowed out of bed.

Before this change happens, the clock shows it i s still night time and therefore your child should be in bed asleep (or at least quiet and not disturbing the rest of the family)

The clock is objective and can’t be argued is either 'morning' or it is not.

Using a sleep trainer clock becomes an essential part of your bedtime routine – putting the clock ‘to sleep’ and saying you will see it wake up in the morning reinforces the message about staying in bed both at night time and in the morning.


How can the child tell it is morning?

It depends on the clock. With the Gro Clock the the stars display on the screen countdown and change the moon face on a blue coloured screen to a smiling sun on a yellow background.


Choosing which sleep trainer to buy

As with most things electrical, there is a strong element of ‘you get what you pay for’ and budget is always a factor. Also have a think about which clock you like and your child likes the look of.

Here’s a summary of our current range:

When it's time to wake the display colour changes and the moon changes to a picture of a sun.

Introducing a Sleep Trainer Clock

For the most effective introduction, we recommend you change the time gradually over the first week or so.

So if your child currently wakes for the day at 5.30am, we recommend setting your sleep trainer for say 5.40am on the first day. So after a short wait, they will see it is morning time. Congratulate them for waiting until the clock says it is time to get up. get up and start the day! Then set the clock for the next morning to wake up at 5.50am, and the next day at 6am.

And as with any sleep training, parental consistency is always the key! So while the clock will be an excellent tool, you can’t set the time for 7am tomorrow morning and expect that your child will instantly start to sleep in! You may need to go in and remind them to stay in bed until the clock says it’s morning. Or repeatedly put them back to bed or sit with them and wait until the clock changes. This initial assistance will pay dividends quickly.


What age can I introduce a Sleep Trainer clock?

It depends a lot on the child but generally from about 2 years old. The key is when your child is able to understand what the clock means - for example, if the Claessens clock is illuminating the picture of the sleeping bunny, that means stay in bed and get up with the picture of the awake bunny is illuminated, or when your child can tell the clock being yellow means the day has started and blue means stay in bed/asleep.
