My teething sick boy, again

Its been a rough week here since last Tuesday. Jay and I were just so happy to have our refreshing weekend gettaway and coming home was just dandy as everything went so well and we were happy to be with our kids again and enjoying that we were all doing so well...until...
Tuesday night Rylec had thrown up and there it was... the flu in our boy, once AGAIN. So we went about taking care of him as we know how to when your baby has the flu, but its been a long one this time and its taken us up and down a rollercoaster of wondering when its really gonna be over. At this point its still not for sure over. We are thankful that he's not severely dehydrated and he has kept a little down, but he seams to have a pattern now of throwing up once a day and acting very fatigued. Its breaking our hearts to say the least and we're just trying to be strong and realizeing it will have to end eventually and if it hasn't after two weeks or if we see any sure emergency, we WILL take him in, NO DOUBT!
(btw, that decision is a result of asking the phone nurses what to do multiple times, and from learning in our past that going to the doctors or ER room is honestly NOT always best)
