B.S.
I had mono when my youngest was just a toddler. I was worried about him, and my other children, but the doc said that mono in young children was seldom very bad. Now for adults, that's a different story.
For you, I gotta say it is hard, but you have to rest, rest, and then rest some more. I tried to keep up with my toddler and the house work, and I just couldn't get over it. Finally I just gave up. I took care of my toddler's needs during the day, then my children came home, and I asked them to take over. They did. Then hubby came home and did dinner, and they all did the dishes. My house was a mess for 2 weeks, but I did not start to get better til I started to seriously take care of myself and rest. I mean, it was exhausting to lift my index finger, and I am not kidding. So, if you feel like you are not getting better, REST!
