SherryRisty,
You should definitely call his endo. He should tell you when and how to administer more meds to your little one. I never hesitate to ask my daughters endo anything, and he is more then happy to answer. Even if your endo seems bothered by questions, you should still ask! It’s his job to be there for you and your little one.
Our endo told us to administer a double dose any time she had her immunizations. Keep asking questions and never seem bothered by asking more! It’s better to be safe then sorry. :)
Sherry
