A toddler comforted her mother suffering from morning sickness and patted her on the back. <br /><br />Katherine Hagen, 32, was pregnant with her second child when her daughter, Rosie Hagen, 2, came to comfort her. <br /><br />A video shows young Rosie patting her mum on her back and saying "It's OK, it's OK."<br /> <br />Katherine had bad morning sickness throughout her pregnancy and Rosie took to comforting her whenever she could. <br /><br />Katherine, a procurement agent from St Louis, Missouri, USA said: "Rosie has got used to me being sick so she comes in to comfort me all the time.<br /><br />"Whenever I go into the bathroom she'll come in to rub my back like in the video."<br /><br />Rosie learned to do this from Katherine, who does the same thing when Rosie isn't feeling well, and even sometimes pretends to puke, just like her mum. <br /><br />Katherine is very proud of her daughter for showing so much empathy and emotional maturity. <br /><br />Katherine said: "She's mirroring what I do when I comfort her, she goes to the bathroom to pretend to be sick so I can rub her back as well. <br /><br />"It feels really good to have her say this, seeing everyone's feedback is great It really makes me proud to see her being so compassionate."
