Sterilize the cup
Choose a method:
- Boil water in a pan. Place the cup in boiling water for 3-4 minutes, making sure it does not touch the bottom of the pan.
- Place the cup in a bowl/mug. Pour boiling water in to cover the cup and let sit for 3-4 minutes.
- Place the cup in a microwaveable bowl/mug, add water to cover the cup and microwave on high for 3 minutes.
Let the cup cool down before use
Just a reminder, this would be more comfortable to do with short nails!
