Everyone is born with open chakras, and children often exhibit natural gifts until they are ignored or generally not nurtured. It's not uncommon at all.
An example would be a baby feeling the energies of a nervous family member when they are holding them and the baby reacting to those energies by crying.
every psychic i meet saids i was born with my third eye open,my magick teacher saids i was born with it open,and i can sence,see,and comincate(bad spelling) with spirits,and i can sence the future a little
Rash,babies know the energies cause its part of develoment,and babys act like that for there age and everyone has a third eye,but not many people are born with it open
Unless there was some traumatic birth event or some karmic reason, all children are born energetically open: chakras, meridians, etc. I would bet that most children are born with their third eye open.
(AND having an "open" third eye does not mean you have super woo-woo psychic powers. Seeking to "open" your third eye does not make you more psychically in-tune. Chakras are a part of your anatomy - people ascribe certain extra powers or emotions to them, but that is not the end-all-be-all around chakras. It is like saying having large feet make you a better athelete - perhaps yes, perhaps no.)
Everyone has something that they are good at. Whether it is attuned to something to do with the magickal path or with sports, or with general knowledge such as match or english is of little concern. People use the talents given to them for the purposes they see fit. Don't freak out because something about you is different, or see it as some monumental calling. See the talent for what it is.
If you think it is something more, than don't ask people who don't know you about it. Ask yourself, your spirit guide, your dieties. Only those who truly know you can answer something about you with complete truthfullness.
