What can I do to ease my baby's symptoms?

Try holding her in a more vertical position while feeding, and keep her upright for a bit right after feedings, too. (Don't put her down for tummy time or a nap – or even a diaper change – right after she eats, for example.)

Giving her less breast milk or formula at each feeding may help, too. You can make up for the smaller quantity with more frequent feedings. And make sure to burp her until you get a good burp after every feeding.

Ask the doctor if you should thicken your baby's breast milk or formula with a little infant cereal or use a formula that comes with "added rice starch." (The doctor will explain how to mix the cereal into milk or formula. You'll also need to use a bottle nipple with a wider hole or variable flow to allow the thickened fluid through.)

Keeping your child away from tobacco smoke can reduce reflux symptoms and is a good idea anyway.

While other parents may suggest letting your baby sleep in a car seat, experts don't recommend this because it seems to put more pressure on her stomach and may increase reflux symptoms.

In fact, experts generally don't recommend letting your baby sleep in a car seat, bouncy seat, or swing – even strapped in – because these products have not been studied for that purpose. They may have padding or inserts that pose a suffocation risk, and the baby could move enough to flip a car seat over when it's not installed in a car.
