Kind of on the same note, but I can tell from a mile away ds 2 is getting sick, but with ds 1 you just dont notice until he is showing major symptoms. When he starts getting sick he will either be grumpy, unwilling to do anything, not very obedient just some random no good attitude and then a day or so later, oh I see, you were getting sick. It is odd, but ds 2 gets this look about him and does and and says really predictable things and ds2 acts like a jerk and doesnt think to tell me he doesnt feel well.
