Hello. My 15 month old son has a pimple like bump on his hand that I noticed this afternoon. I thought it might be an ant bite because it was next to a very small dot that looked to be an ant bite that maybe got scratched open. Now (about 6 hours later) the small dot I thought was an ant bite is also starting to form into what looks like a pimple. Do you have any idea what this might be? I don t feel like this is emergency room serious, but I am also scared if I don t take him in he could wake up in the morning with a lot more of these bumps.
