Make sure to stir the formula slowly so that you minimize the number of air bubbles that form.

Pouring the formula slowly also helps to make sure that the liquid does not trap air as it gets poured into the bottle.

Stir the formula with a wooden stick or knife to make sure that it is mixed in well.

Preparing your baby’s formula ahead of time will keep you from rushing through the preparation process. When you rush, you are more likely to stir the formula quickly, which causes bubbles to form.

“Mylicon” drops are commonly used for this purpose. These drops contain simethicone, an ingredient that helps the breakdown of gases and air bubbles, and is not harmful for babies. “Tummy calm” is a homeopathic medicine that prevents gases with the help of natural ingredients like chamomile, thuja, and silicea. Gas drops can be expensive, and some studies suggest that they may not be very effective. However, they appear to be safe, so they shouldn’t harm your baby if you do decide to try them.

Always make sure that the bottle is full of formula or milk so the baby is not taking any air from the bottle. Even the bottle nipple should be full of fluid and no air.

Generally, you want to aim for a 45 degree angle, but this will change depending on how much milk is in the bottle.

Fill the bottle up with milk or water. Turn the bottle upside down. The flow should be approximately one drop of liquid every second. You should get a new bottle if the liquid stops and starts flowing constantly. This will cause your baby to struggle to suck out the liquid. If the liquid flows without stop out of the bottle, there is a chance that your baby will not be able to catch her breath. This is also a problem.

The ring may need to be loosened a little bit in order to allow your baby to suck out the milk. The ring is tight enough when you can see a large bubble forming every time your baby takes a drink. If it is not on properly, you will see a bunch of bubbles form as soon as your baby stops trying to suck the milk out of the bottle.

Use a bottle with a valve at the top. This valve allows just enough air to enter the bottle so that your baby can drink easily, without consuming any air bubbles.
