I just want to no my step dad died recently and my 8month daughter is starting to smile and wave at things that aren't actualli there is it possible that she can see his ghost ?

Personally, I would be inclined to say that if you believe she is, she probably is.. I believe that sometimes children can see what adults cannot.

Yes, although ghost isn't quite the word I'd use. The belief is that all children are born with a sixth sense, and life, adults and people disbelieving gradually closes that down. Some adults still don't see, but 'feel' - look up Empaths. Some people are fortunate enough to still retain that 'third eye', and still see and hear the shades of those who've passed - it's like a residual 'energy imprint' left behind. Be happy he loved her enough to hang around a while longer, she's lucky to be so loved:)
