Why is milk different from one mammal to another?

Video · 1:52 · Crafty Clover explains, from A Million Whys Book 33

Every kind of mammal has its own milk recipe. A rabbit mother feeds her babies only once or twice a day, so her milk is very rich in fat and protein. Some mothers nurse their babies all day long, and their milk has less fat. People’s milk has a different mix than cow’s milk. Each recipe fits how fast the baby grows and how often it feeds.

What Crafty Clover says in this video

Intro

Hi there, curious minds! I'm Crafty Clover! Let's discover something amazing. Why is milk different from one mammal to another?

The Big Idea

Rabbit milk, seal milk, cow milk! They're not all the same! Why is milk different for each mammal?

Rich Rabbit Milk

Step one: Rich Rabbit Milk. Every kind of mammal has its own milk recipe. A rabbit mother feeds her babies only once or twice a day, so her milk is very rich in fat and protein.

Thinner Milk

Step two: Thinner Milk. Some mothers nurse their babies all day long, and their milk has less fat. People's milk has a different mix than cow's milk.

Fitting the Baby

Step three: Fitting the Baby. Each recipe fits how fast the baby grows and how often it feeds. Babies that must grow fast in cold places, like seal pups, get super rich milk.

A Closer Look

Let's take a closer look! Very rich. Super rich. In between. Thinner.

Quick Facts

Quick facts! A hooded seal's milk is more than half fat. Rabbits nurse only once or twice a day. People's milk is different from cow's milk. Each recipe fits the baby.

Think Like a Scientist

Now, think like a scientist! Imagine you're a milk scientist. Make a chart with three animals. Write whether you think their milk is thin or rich. Give a reason for each. Check a book later.

Outro

Every mammal has its own milk recipe. Rabbits nurse rarely, so their milk is very rich, while mothers who nurse all day make thinner milk. Each recipe fits how fast the baby grows and how often it feeds. Science is amazing! Keep wondering and keep exploring! Share what you learned with someone at home, and see what they think!
