Yeah her baby sounds pretty much like almost every newborn, and at the stage she's at, babies do not give a hoot what time of day it is, they'll nap whenever, and sleep whenever.
I tried to get my baby into a routine of going down for the night before my toddler and it just did not work out at all! if the baby isn't tired, they aint tired and theres absolutely nothing you can do about it, you just have to stay up with them until they go to bed, even when you're ill and just begging for an early night.
He really doesnt sound that 'bad'.
