Sick again

So, its never fun when a child is sick - only a mom knows what she goes through - it is always hard to focus on anything else. And so it has always been with me and the kids if and when they get sick. I have been relatively lucky with the older one and younger also has a strong immune system, despite the seizures and the other issues. The other day he fell sick - my heart beat almost stops even now when he is sick - I am not as paranoid is what I would like to believe - but two nights ago when he threw up about 8 times, I was on tenterhooks - I am still just relieved that nothing else happened. There was no fever, nothing else - but he just kept throwing up and when it stopped at about 1:30 - just like from about 10 pm - I couldn't sleep because I kept thinking - he is now going to throw up again. It was a nightmare - I guess making up for all of those healthy days he has seen the past several months.
In any case, God is good, all's well with the world and he is hale and hearty again - yelling and screaming and as normal as he can possibly be.
It is obviously a challenge during his throwing up phases - he is anyway on a restricted diet, combined with the throwing up - what can he eat when ok? So when he awoke the only two things he was allowed was apple and banana. Two hours thereafter, when he was still doing fine, he was allowed his cereal, thereafter salad and yogurt, thereafter his nuts.
I am truly grateful everything was shortlived and I can go back to thinking that this phase never happened at all.
