That is great news, that it can be checked at her next appt. That means it really is nothing. However, if Jaelynn's parents are really worried, they should just schedule a sooner appt, and have her looked at by the doc. Being a parent involves enough worrying, and no need to worry more about this.
When (now 6 y/o ds) was just a few days old, I remarked on how calm he was, and how he didn't even react to loud noises. DH said, "Maybe he's deaf." I burst into tears. DH's baby brother is deaf, and so to him, although he did not want our son to be deaf, it was not a huge worry. He just figured we would check when ds got older, and in the meantime keep watching for signs. Well, I called the doc, and they scheduled a test to check his hearing (which was just fine.) Doctor's understand that parent's worry. They will see her sooner if needed for Mom and Dad's peace of mind.
