Does my seedling look healthy?

He or she is around 6 days old (After breaking the surface). I have been putting it in as much sunlight as possible, only watering when necessary. No prolonged periods of being exposed to artificial light. I'm worried he or she is too small for its age.

Thank you guys! First time growing my own and I was paranoid about the height of my plant. I thought the hairs were a problem xP, silly me!
