Best formula for sensitive tummies

What you feed your baby is arguably one of the most important decisions you'll make.

If you’ve chosen to formula feed, you’re likely overwhelmed by the options you have to choose from. With each product promising to provide the best nutrients and vitamins for your baby, new and experienced mothers alike are left wondering which brand is really best.

Why you should take this decision seriously

Though it might feel as if all baby formulas are the same, your baby may not react to all of the formulas the same.  With various types of formulas each containing their own combination of ingredients, some may not agree with your baby’s digestive system.

When it comes to formula, some babies require a special kind due to food allergies or sensitivities, and many babies have sensitive stomachs that demand special care. Selecting the wrong formula for your baby could directly result in anything from an upset tummy and diarrhea to vomiting and other allergic reactions.

In order to minimize troublesome stomach symptoms, parents should take advantage of special formulas.

Signs your baby has formula sensitivities

How do you know if your baby is suffering from formula sensitivities or allergies?

Though each child may have a different reaction that ranges from mild to severe, parents should pay attention to signs such as these listed below:

  • check
    Dry and itchy patches of skin
  • check
    Hives
  • check
    Swollen mouth or lips
  • check
    Diaper rash that won’t go away
  • check
    Extremely fussy after eating or struggling to pass gas
  • check
    Uncontrollable crying

If you notice these symptoms in your baby after feedings, it’s possible that they have had an allergic reaction to the formula and/or they have sensitivity. If they’re experiencing extreme reactions like swollen a mouth or lips, extreme diarrhea, or vomiting, immediately contact your child’s pediatrician.

Tips on switching baby formulas

Switching formulas is the most effective solution to prevent your baby from getting sick. This should not be done without first talking with a doctor. Depending on the severity of the allergic reaction or sensitivity, a pediatrician will determine whether the switch should happen gradually or immediately.

For parents of children with severe allergic reactions to baby formula, you’ll need to switch them right away. Determine which formula is best based on the type of allergy or sensitivity your child has. Give baby a bottle and pay attention to how he reacts. If you don’t notice any of the above-mentioned signs of an allergic reaction or sensitivity, you can continue feeding baby the new formula.

For parents who have decided to gradually switch their baby’s formula, start by giving the baby one-part new formula to three-parts old formula. After a day or so, if you don’t notice any additional reactions to the new formula, you can increase it to two-parts old formula and two-parts new formula. Continue this pattern until the baby is drinking nothing but the new formula.

If you notice changes in your baby’s health as you’re switching formulas, do not try another formula without first talking with a pediatrician. Mixing too many different formulas can make it more difficult for doctors to determine what ingredient your baby may be most sensitive or allergic to.

Choosing a special formula for your baby

After speaking with a pediatrician, if it is determined that your baby is allergic or sensitive to ingredients in the formula, they will likely recommend that you use a special formula for certain allergies or sensitivities.

The best formula for sensitive tummies benefits your baby as it can make him less irritable, prevent him from becoming constipated and uncomfortable, and improve his digestion overall.

When you’re buying formula for any baby, you should consider the following factors:

  • Medium - Should you use powder, liquid concentrate, or ready-to-use formula?
  • Vitamins - Does the formula contain iron, vitamin D, and other beneficial vitamins that your baby needs to be healthy? Does it contain DHA?
  • Ingredients - What ingredients make up your formula choice? What types of oils and probiotics does it contain?

When you’re buying formula for a baby with a sensitive stomach, you may want to consider additional factors, such as the below:

  • Organics - Is the formula FDA organic certified and does it contain GMOs?
  • Treatment - What symptoms is the formula proven to relieve?
  • Ingredients base - Do you need a milk-based formula or something soy-based and lactose free?
