Pepcid Complete vs. Mylanta

One more question 🙂 I gave Cade Mylanta last night hoping that it would help him to sleep through his 4 a.m. screaming ritual. It did prevent the screaming, however it gave him a tummy ache so he was up squirming around anyway. I’ve read that Pepcid Complete works better anyway, but all I can find at the drug store is in tablet form. He’s too little for tablets (and, perhaps, too little for Pepcid) Has anyone given it to a young infant and, if so, how? I will discuss with his doctor tomorrow before giving it to him, but they are not terribly supportive of giving him ANY medicine, so I’d like your opinion as well.

Thank you!
