Well, nothing is impossible, and any drug can cause nausea and vomiting. It
would not be the first thing I thought of in a spitting up baby. The fact
that the baby did not spit up after bottled expressed milk does not prove
anything, since the method of delivery is different. I have followed a
number of mothers on sertraline, and none of the babies reacted this way.
But, maybe.
