Ds 5mo keeps grabbing at or putting his hand over his right ear and his other hand on the top of his head, starting in the last couple of days. He's not crying doing this, has no temp and there's no discharge from the ear. He is his normal self. I'm worried that it could be an ear infection and unsure what to do. Or is this just a developmentally normal thing as he learns to use his body? I'm a ftm so feel rather anxious about this. Thank you.
