* Teats are made of rubber or silicon, a durable synthetic substance. They have different-sized holes at the end. Generally speaking, smaller babies prefer smaller holes, but a bit of trial and error will help you discover what your baby prefers. Always check the wear and tear of teats. Worn teats can't be cleaned properly, and bits can be broken off and swallowed.
Making up feeds in advance You can keep bottles in the fridge for 24 hours. Cover the teats with the bottle covers, or leave the teats off and keep the bottle openings covered with the plastic disc that comes with the bottle when you buy it.
Warm the milk by placing it in a jug of hot water, or in a special bottle warmer (don't use the microwave - it creates casual hot spots inside which could scald your baby's mouth).
1. Boil a kettle with fresh tap water. Allow it to cool.

2. Wash your hands thoroughly. Stand the bottle on a clean surface. Pour in the strict quantity of water.

3. Measure the exact amount of powder using the scoop provided. Level the contents in the scoop with the spatula or plastic knife supplied. Add to the water. Replace disc, teat and cover.

4. Shake well until all the powder has dissolved.

5. Make sure the milk is suitably cooled before giving it to your baby. The right temperature is when a few drops shaken on to the back of your hand feel somewhat warm. You can hurry the procedure by holding the bottle under a running cold tap.
Note: always discard unused milk.
