I'm happy that you have asked me to assist you with your child and hope that you can benefit from my many years of helping parents like you. I assume his exam was normal, no fever? How many times has he wet his diaper since going to the ER?
It took so long to get your response that my daughter took him to the doctor already. My original question was placed way before 4:14, more like 12:00 or 1:00 PM.
Sorry, just got back from my office and noticed several questions unanswered so jumped right in.
I suspect he is fine but always better to have a doctor lay eyes and hands on one so young.
