It depends on your dose, your children’s age, their typical needs from you, and your doctor’s view of restrictions. If your doctor gave you this amount of time away from them, I can only presume they had good reason to do so ~ there are a couple of different considerations when you’re talking about keeping your distance from other people, children and pets after RAI, and I’m sure the doctor took all of those details into consideration when they made the decision. You could talk with the doctor who gave you those restrictions to see if they have any ability to adjust it for you. Still, it’s only a few days away, closer every minute!
