I wish I could help, I know that I would be going out of my mind worrying if this was happening to me. I have no first hand experience with RI but I would think that Leon probably just had water. My understanding of RI is that it is mucus that comes out of their mouth so even if it was mucus it isn't all infected and If he does have Ri it is very early on. AS I said at the beginning I have no experience with RI so take what I said with that grain of salt. I'm so sorry that you are going through this, and wish you the best of luck.
