Not silly at all!
We take breaks playing, Winky, if he could have his way, would play fetch from the time he wakes until the time he goes to bed at night...
So we'll throw a small stuffed toy for Winky now and then, or we take 5-10 minute play breaks for both of them. When Yoda wants to play, which is more rare, I guess we try to tend to that more often, since he wants to play less, if that makes sense...
