Is milk a juice?

img_1836

Milk is a white-coloured liquid food made by mummy cows to feed their baby calves. It contains all the nutrients that a young calf needs to grow – and that makes it a good food for humans to drink too.

In our family, we drink a lot of milk – about 8 pints each week! We put milk in our tea, on our breakfast cereal and in our baking. And we eat other things that are made from milk, like butter and cheese and yogurt and ice cream.

But over breakfast the other morning my 5-year-old was thinking about the milk on her cornflakes and she wondered – is it a juice? So let’s find out…

Where is a horse’s belly button?

Horses graze in the fields near our house. We often see them being walked or ridden as we walk to and from school and my girls like to wave ‘hello’ as they pass. This week, we saw a foal which got my 4-year-old thinking about how horse-babies are born and whether or not they have belly buttons.

Why are humans a animal?

Human evolution was a topic of conversation at the dinner table. My 9-year-old declared that “humans used to be monkeys a long, long time ago”; my 4-year-old worried that she might have monkey children when she grows up.

I explained, as in my answer to Why do monkeys still exist?, that humans have evolved over millions of years, and that monkeys and apes and all other creatures have evolved over millions of years too. I showed her a book called The Story of Life and said that, like other animals, humans have evolved over a long, long time.

She didn’t like the thought of being an animal, so we had a think about what being an animal means…

Why do I have to go to bed?

sleeping

Bedtime is one of my favourites times of the day. For me, going to bed is a time to get comfy and snuggle down under my duvet, head on pillow, for a good night’s sleep. Lovely.

But my daughters have other ideas at their bedtimes – they want to stay up late, read books, watch TV or play games. I insist on a routine of calming down (no TV or games!), cleaning teeth and brushing hair, maybe a bath, a short story and getting off to sleep as quickly and quietly as possible.

And our cat sleeps for most of the day and the night – he thinks sleeping is great!

So why is it so important to go to bed? What good does sleep do?

Do sharks hibernate?

Hamsters are the latest pet obsession in our house – the 8-year-old wants one but Daddy has said “No”.

The girls have friends and cousins with hamster pets and they know lots of facts about the furry little creatures. “Apparently, they hibernate in the Winter” our eldest told us, as she and her sister┬átried to list all the animals they could think of that hibernate. “But what about sharks?” asked the 4-year-old. “Can they hibernate?”

Can cats burp?

Burping (or, as some people call it, belching) is a normal part of being a human being. Everybody does it. That’s because when we eat and drink (especially if we’re talking at the same time!) some of the air that we breathe gets swallowed down to our stomachs. And then, that air has to find its way back out of our bodies. It either gets pushed back up to our mouths and comes out as a burp, or it gets pushed down to our bottoms and comes out as a fart.

But my girls want to know if humans are the only animals that burp. What about cats and dogs – can they burp too?
