I guess it's not uncommon for second kids, but K2 got interested in toilet training unexpectedly early. We've been taking it super low-key, letting K2 set the pace and be interested in it when she wants. But we were kind of caught off guard, and so when we first needed it one night, the only candy we had in the house for our little reward/congratulations system was M&M's. [That's what we call them, "congratulations."
Which would be fine, except they were custom-printed M&M's with pictures of the kid, which my dad had sent as a birthday party favor. As we worked our way though the little bag, I kept wondering what the unintended psychological impact might be on K2 of receiving candy with her big sister's picture on it every time she successfully went to the bathroom.
Once we really step up the pace and make using the toilet the norm and not just a hobby, I figured it'd be better for K2 to have some dedicated congratulations of her own.
So I went to the M&M's customizing website, which is ridiculously easy to use [unnecessary disclosure: my dotcom-era firm built M&M's first website, including their first webshop, where you could custom-mix colors--by ordering any single-color, 5 lb. bags you wanted.] and thought I'd order some pee and poo congratulations. Except that M&M's considers those terms inappropriate for some reason. I know, I can't figure it either.
So I scrapped the whole idea, and we'll just use off-the-shelf M&M's. But since the site was so easy to use, and there was a Labor Day weekend sale, I couldn't resist ordering some treats to congratulate my web designer friend for his recent mastery of the websafe color hex table. Look at that, there's even an M&M's ad on this page for #33d!
