Looks like the boys are having a blast Dicky. Sincerely happy for you that Camo and Gauge are getting along. Just curious, is Camo possessive of your son attention?
In my case, my oldest granddaughter who spends lots of time with us, has always had a special relationship with Titus and he watches her like a hawk. When we added Athena to the mix anytime my granddaughter would give any affection to Athena, Titus would make his way in between them. He was "peeing on the fireplug", so to speak and letting Athena know this was his. He now just shares but he did it for sometime in the beginning.
