My sister also had a very wakeful baby.Kate would only sleep very little during the day, preferring to not miss a thing that was going on!During the night she'd sleep very little as well, which was odd for a formula feed baby!
I did read somewhere that 'gifted' children apparently sleep very little.Maybe you have a genius on your hands!My neice is very artistic and a real little adult already!I remember she was trying to feed herself from a really young age!
