Hot water bottle

A hot water bottle is a special rubber bottle that is made to hold hot water. The bottle has a special lid that helps you fill it up, and then you put it on your tummy or hold it close to your body to keep you warm.

When the hot water bottle is filled with hot water, it gets warm and cozy. You can hold it close to your tummy or cuddle with it in bed to help you sleep better. Sometimes people use hot water bottles when they have a tummy ache or cramps because the heat can make them feel better.

It's important to be careful with hot water bottles because the hot water inside can burn your skin if it's too hot or if the bottle breaks. Always ask a grown-up to help you fill it up and check the temperature to make sure it's safe to use.
