Sheldon and Amy's kids

We know from a few lines on Young Sheldon, including last night's episode, that Sheldon (presumably with Amy) has children. Though this show really didn't need stretched out further, too bad we didn't get to see that. Would've been hilarious and delightful to see Sheldon's schedule completely thrown out the window and him having to deal with it and it not being something that could be resolved in an episode. Then again, they didn't want the show to become all about kids with is why we didn't see the Wolowitz kids until the end.
