My dh works shifts and so every 3rd week he has to do nights. This is fine except he spends the whole week walking round like a bear with a sore head cos he has been up all night. I have tried to explain to him that I have been up all day and by time I get to bed it is midnight and I am up at 6 this is if ds goes through the night whereas he goes to bed at 7 and gets up at 4! Therefore during night shift week it is me surviving on less sleep than him but I guess thats just me being unreasonable!!
