That site does have a Children’s Mylanta listed, but it may not be carried by most pharmacies.
I actually *finally* found it today!!! It is the store brand version, but there was no Mylanta version. We’ve also decided to stick the soy we were on (thanks for your other response explaining if/then’s :)) with oatmeal cereal in it and Mylanta after she eats. We did that for the last two bottles, and she seems to have been a bit better than usual. We’ll see how the next few days go.
Thanks!
