Our Punkie and Chloe both suffer from acid reflux and occasional indigestion. Their symptoms were throwing up food followed by throwing up bile...sometimes they even slober excessivly due to the upset stomach. Ours two girls take a 10 mg generic Pepcid AC each morning and if they show signs of indigestion, another 10 mg. an hour before bedtime. Our vet prescribed Pepcid AC and it has worked like a charm...no more upset tummies. If you have Pepcid AC at your house, you could tell your son to give your boy one tablet hidden in a bite of lunch meat, hot dog, peanut butter, cream cheese...whatever he likes. Good luck with your baby...hope he feels better soon!
