DS (nearly 9 months) is putting me through the sheer hell delights of sleep deprivation again.
I'm finding it increasingly difficult to be the kind of parent I want to be... lots of shouting, no patience, no smiles... 
I try to nap when DS does (also have 2.5yo DD too) but this really only just takes the edge off, and probably isn't sustainable much longer!
Please tell me how you get through the days/weeks.
