Your ears probably can’t take any more of your baby’s high-pitched cries.

Your little one is stressed and fussy while stooling. Baby’s tummy feels harder than usual, and he/she hasn’t pooped in a while. Or the baby might cry or sometimes appear to be red on the face from straining.

All these symptoms are signs of constipation. And the formula you're using is most likely the culprit!

It may take up to a week or so for a new formula to take effect, so be patient! It is essential for both new and seasoned mothers to choose and stick to a trusted brand. These brands, such as Similac, come in a variety of flavors, leaving parents wondering, "Which Similac formula is best for constipation?"

The good news is (well, not for me) that I tried about seven different formulas for my gassy son before finding the one that worked for him.

So, after reading this guide, you should know everything there is to know about the best Similac formula for constipation. And you should no longer struggle to find a reliable and safe Similac formula for your baby.

What causes constipation?


Because a baby's body is still developing, it needs to stay hydrated. If not, the body will absorb fluids from foods, drinks, and even waste, hardening the poop.

Introduction of solid food

Introducing new foods to the baby can frequently cause constipation. Constipation can occur when insufficient fiber is in the diet to aid digestion.

Formula milk

can you mix colostrum with formula

Constipation is more common in formula-fed babies. Because the formula is more difficult to digest than breast milk, resulting in a firm and bulky poop. It's not unusual for your little one to become constipated for a short time when transitioning from breastmilk to formula. When making a bottle of formula for your child, it's critical to follow the instructions on the package. Too much powder can dehydrate your baby, which can contribute to constipation.

Underlying health conditions

Your baby's digestive system problems are less common. That is why you should see your pediatrician whenever you suspect something is wrong. So you can get medical advice and be sure of what your baby is dealing with. But don't be concerned; this affects less than 5% of babies and is usually easily diagnosed by a doctor. Your baby's constipation is much more likely to be caused by one of the above issues, which is easily treated.

Genetically changed ingredients may have higher nutritional value, grow faster, be more resistant to diseases, or perform better in other ways.

Suppose traditional formula causes the baby to develop GI symptoms because of a milk allergy or intolerance. In that case, Alimentum may provide relief while still providing all the vitamins and proteins the baby needs.

Similac Alimentum contains few or no allergens, hence the term Hypoallergenic. It is lactose-free and is intended for infants with food allergies or colic caused by protein sensitivity. It is easily digested and absorbed.

Cow's milk proteins are still present in Alimentum, but they have been broken down to make them easier to digest. The formula is also intended to aid in developing the baby's tolerance to cow's milk proteins.

Alimentum, like all the brand's products, does not contain palm oil, which is thought to stiffen stools in some infants and reduce the amount of calcium and fats absorbed into the baby's system.

When a baby switches from a standard formula to Alimentum, the symptoms caused by the standard formula should disappear within 24-48 hours. It is one of the specialty formulas that doctors most frequently recommend.
