Happened to me once, having serious dehydration due to food poisoning and got send to hospital by ambulance as I am shivering non-stop with bad cramp and low blood pressure. Stay in hospital for half day for drip and got to travel home alone to take care of kids. Lucky Husband is able to stay home that day to parent the kids while I am in hospital. Mommy don't entitled to off or sick day specially Mommy with no help from parents, parent-in-laws or helper.
