After drinking two sippy cups of juicy juice with DHA, my two year old son screamed with a hard tummy and vomitting for an hour. Is this juice too strong for little ones?

Anon, I'm so sorry! He was screaming for an hour? That gives us such distress when we aren't sure what's going on and when or how it will stop. Poor little thing.

For those who aren't sure what DHA is, it's short for docosahexaenoic acid. It is an omega-3 fatty acid that may be beneficial for children's brain development.

On the Juicy Juice web site, it specifically says:

"Nutrition Facts
"Baby Steps: Critical brain development takes place when your baby goes from six months to two years old; Juicy Juice Brain Development is specially formulated for this early age group.
"DHA: An Omega-3 fatty acid especially important for brain development in children under two years old."

So it's definitely meant for your son's age group. The only group they caution against giving it to is those children who are less than 6 months old. I'm wondering if there's anything else in there you think he might be sensitive to?

Here is the ingredient list for the Grape flavor:
INGREDIENTS: APPLE JUICE, AND GRAPE JUICE (WATER, JUICE CONCENTRATES), WATER, AND LESS THAN 0.5% OF NATURAL FLAVORS, PECTIN, ASCORBIC ACID (VITAMIN C), FISH OIL (TUNA) [A SOURCE OF OMEGA-3], CITRIC ACID, GELLAN GUM.

And here's the ingredient list for the Apple flavor:
INGREDIENTS: APPLE JUICE (WATER, JUICE CONCENTRATE), WATER, AND LESS THAN 0.5% OF PECTIN, ASCORBIC ACID (VITAMIN C), FISH OIL (TUNA) [A SOURCE OF OMEGA-3], MALIC ACID, GELLAN GUM.

If none of those ingredients are things your son has been sensitive to in the past, I'm wondering if by drinking two sippy cups at once he just got too much at once? And either the cold or the sweetness bothered him? Did he eat anything else at the time that might have upset him? Or was it just the juice?

The website does say this about how much to give a young child:
"The serving size for your young child should only be 4-6 fl. oz. of fruit juice per day. Because the US population generally consumes lower intakes of foods rich in DHA when compared to populations in some other countries, it is unlikely that one will get too much DHA in the diet. If you are unsure, consult your pediatrician."

You might try giving him just a spoonful and seeing if he has any reaction to it. If he does, you might save the carton and ask his pediatrician if there's something there he might be sensitive to. And is there a 1-800 or a 1-888 number on the box? You might call their customer help line and see if they have any advice. They do have an electronic "contact us" page if you're more comfortable with that:

Save the carton until you find something out. And please, come back and update us when you figure out what's up, OK?
