Wtf is this ?

Hannah • Married to a wonderful, hard-working man, with a rainbow “ours” baby boy 07/11/19 🥰 and two beautiful step daughters. 💜

okay, so my husband's children are so sick when we get them for our weekends. Coughing, snotty nose, throwing up, headaches.. But the mother says they don't do any of this at her house. We've tried getting her to take them to the doctor but since nothing is wrong on her side, she doesn't see the point. We have no idea what to do. Any suggestions??? please help
