Hello I have gone through your complaints. Your child didn't present initially with symptoms like vomiting
and decreased activity. Initially they will present with vomiting. As you have examined that your child is sick some what, you need to examine him closely for another 24 hrs. If you see like your baby is running of fever
or any vomiting or decreased activity , you need to contact your doctor for an antibiotic.
Thank you. Good day. Take care of your child
