Well this is a little late on the update, but on April 23 Nate had tubes put in his ears to help with the frequent/constant ear infections. It has been such a blessing, he hasn't had any problems since. Its going to be a bit harder to go play this summer in the pool and at the lake because he'll need to wear ear plugs, but its so worth it and I am sure he will get used to it... Hopefully!
He had 6 ear/sinus infections between December and April, and since then he's not had any, a couple random days of fevers, but nothing more than about 24 hours. So definitely worth it!
