I am so sad but just looked up on google, coping on little sleep and this health.ucsd.edu/news/2002/02_08_Kripke.html came up up.
Was looking it up as DD3 has now gone from the perfect sleep through the night baby, to the party animal of the night ArGGHHHHH.
Least this could mean it's better to have little sleep although I feel like shite!!
