"Today is National Doughnut Day!" North West's mama wrote on Twitter. "Thought I would enjoy it more but morning/all day sickness really ruins things! LOL Maybe it's for the best!"

On Tuesday she wrote: "So f–king sick today on all levels!!!!! UGHHHHHHHHH I can't deal!!!!!!!!!! Praying I get through the day."
