Hi all!

Does anyone know if giftedness is passed down? Both my daughters, albeit young, look as though they may be gifted. Both my side and my husbands side of the family have either gifted relatives or really clever relatives, would this make it more likely for them to be gifted? On my side it's me, my mum, both my grandads, not sure of my husbands side but it has come up. Or is it just a coincidence and I have to wait it out? I'm admittedly struggling juggling, my two as they are hard work and I could do with knowing something so I can help myself more as well as them.
Thanks in advance!
