Yes, it is generally safe for babies to drink cold formula, as long as it is properly prepared and stored. However, some babies may prefer formula at a slightly warmer temperature, as they may find it more soothing.

When preparing the formula, it is important to follow the instructions on the package carefully. This includes using the correct amount of water and powder and sterilizing the bottles and nipples. If the formula is not prepared correctly, it can contain harmful bacteria that can cause illness in babies.

If you are using powdered formula, you should mix it with water that has been boiled and cooled to room temperature. The formula should then be stored in the refrigerator until it is ready to be used. If you are using ready-to-feed formula, you should store it in the refrigerator until it is needed, and then shake it well before serving it to your baby.

It is generally recommended that you warm the formula before serving it to your baby, especially if they are very young. This can be done by placing the bottle in a bowl of hot water or using a bottle warmer. Warming the formula can help to make it more palatable for your baby and may help to reduce the risk of infant acid reflux.

However, if you are in a situation where warming the formula is not possible, it is generally safe to give your baby cold formula. It is important to shake the procedure well before serving it, as the powder may have settled at the bottom of the bottle. You should also check the temperature of the formula before giving it to your baby to make sure it is not too cold.
