There is no mention in the article that the doctor thought the baby might have meningitis nor were symptoms consistent with that possibility mentioned. So I have to ask, where you are pulling your information from?
There is also the consideration that bringing an infant/toddler to the ER can expose them to lots and lots of nasty germs increasing their risk of contacting a serious illness.
And the child was better.
