My boy is sick

Landon has been so sick this week. It started with croup last week and then when on Sunday he acted very well, by late Monday he was running a low grade fever. Tuesday morning it was up to 103.8 so off to the Pedi we went. Landon was very lethargic and whining. Dr. T took a good look at Lan and said he has a swollen spleen and that it is either mono or another viral infection. No cure other than Motrin and Tylenol and of course time. Well here we are late Thursday night just when I thought he was getting better now his head is very congested. He hasn't eaten a meal since Monday and is now not wanting to drink anything because it is hard for him to breathe when he is trying to swallow. I am going to take him back to the Pedi tomorrow to make sure that he doen't have an infection on top of what he already has. Last night he was up and down a million times screaming when he would wake up. It is almost midnight and he has already been up twice, so it looks like another long night here. I just want my baby boy to feel good again!
