As the topic says, I noticed 2 days ago that my 3 month old DS's pupils were a different size. The next morning they looked the same size but again yesterday afternoon I could see a size difference. Has anyone come across this? When you google it, a whole stack of hardcore scary things come up but my little boy seems on track developmentally so I don't want to overreact and rush him to get scans if it's not necessary. Wondering if I should call healthdirect for advice on how to react. Any suggestions from bubhub world?
