How Much Sleep Do Kids Need?
Julianne Robertson investigates the world of snoozes, forty winks, cat naps and snoring. What is SLEEP, why do we need it, and how much sleep do kids need?
A couple of nights ago I was feeling really, really tired, so I went to bed early. I slept soundly, without even dreaming, until about 5am, when I woke up. It felt like I’d only been sleeping for about 5 minutes! After that, I fell back to sleep but had lots of vivid dreams and when I woke up a couple of hours later, it felt like I’d been asleep for a long time. After all that I still felt well-rested and was ready for the day.
All this made me wonder – what IS sleep? Why is it that some nights we feel like we’ve had a really good nights’ sleep, while other nights we still feel tired when we wake up in the morning? Here’s what I’ve discovered about sleep…

As such, she invented a range of gadgets to make jobs easier, including the pedal bin in the 1920s. Now we have to admit, pedal bins aren’t very exciting, but Lillian’s life definitely was.
The Contronym – a Word that Bends Over Backwards
I expect most of you have heard of antonyms, and even if you haven’t heard the word, you know them and use them every day. Antonyms are words that mean the opposite. For example, hot is the antonym of cold, rich is the antonym of poor.
But what happens when we have a word that doesn’t have another antonym – it is the antonym of itself?! You are probably wondering what on earth that could mean. Well, there are some words that have two meanings which are the opposite of each other. This makes the word its own antonym. Words like this are known as contronyms.
LEFT
Left and Left Behind
One very common one that we shall start with is a word that you use all the time without ever thinking about it being a contronym. This is left, which can mean “gone, departed” or “still there, remaining” . If you have gone, then you have left, but if everyone else except you has gone, then you are left!
