Jax is sick

My little Jaxalope is sick. He's on day 6 of diarrhea. I've been monitoring him for dehydration and so far, so good. He goes through cycles throughout the day when he's doing better than others, but for the most part he's happy! He's been sleeping most of the day for the past week. Its brutal because he really only wants to sleep on someone. All day Tuesday he slept on me. By Tuesday night he was fine! It was great! Wednesday he woke up all happy. I had to take my parents to OC to help Justin and Lynn with their drive to WA. Brett took Jax to his parents' house so they could watch him while he slept. I took Maryam with me so she could go to Disneyland like I had promised her. I figured it was OK because Jax was feeling better!
Jax woke up every 2 hours last night wanting to eat. He's been on Pedialyt for days and he doesn't feel as satisfied with it as he does his formula. This morning he woke up all happy again and since he hadn't had any diarrhea in over 24 hours I gave him formula. BAD IDEA. He threw it all up (I had forgotten what its like to have a baby that can actually vomit...GROSS) and had 6 diarrhea diapers in 2 hours. Ugh. Back to the drawing board. I'm giving him the Pedialyt every 1.5 to 2 hours and he's not dehydrated. I'd take him to the doctor but I'm fairly certain all he'll say is "Jax has a stomach virus, keep giving him Pedialyt and bring him in at he first sign of dehydration or if his symptoms worsen." (Not my first rodeo.) If he's not better tomorrow I'll take him in and see if they have any new ideas. Poor little guy. He's too sweet and beautiful to have to be sick. I'm sure we all think that about our babies!
