When you buy Similac formula for your child, you will be providing him or her with a healthy and nutritious food source. This is a great alternative to breast feeding that will give your child everything that he or she needs. It is also a good idea to use this formula after you are done breast feeding or in situations in which this is not possible. You need to know how to make it at the right temperature, however, or your child may refuse to drink it. In order to make a new drink, all that you have to do is to mix the powder formula with water. You can put the formula in the bottle first. Then you can put the water in on top of it. This works well because the pressure of the water as it comes into the bottle will cause everything to mix together. You will still need to shake the bottle after you add the water, though, to make sure that everything has mixed evenly. You do not want the child to get large amounts of the formula if they are not mixed with water, as these will not taste good and they could even cause the baby to gag. To get the right temperature, you can run the water over your finger. It should feel lukewarm, but it should tend to be cool on your finger rather than hot. Remember that everything feels colder against your hands than your child's mouth. The skin cells on your hands are thicker and calluses have built up over time. This dulls your senses. Water that feels comfortable on your skin can still be much too hot to drink. The same is true for cold water. It may feel fine against your hand but then it will be so cold it will be almost painful to drink. You also need to have lukewarm water instead of cold water because the formula will mix up better. The powder does not mix well into cold water. It will clump up and it could clog the bottle. You need to find the perfect temperature for everything to work out well.
