Sadly or not depending on how you look at it, both my boys have recently discovered the joys of potty humor. I guess maybe separately they always enjoyed it, but now they wind each other up. Bigmouth has a line of mugs that the kids have been digging. Yes, the mugs are huge and bigger than their heads, but that, I can only assume, is why they are enjoying them so much. The product line also includes mugs that hold cookies or donuts but the boys aren’t ready for that yet (or to be more specific, the Mommy won’t allow). The Ninja mug is of particular interest to BB while the shark bite version is a hit with LTD. All of this doesn’t change the fact that both kids spill constantly when drinking from any mug ever.
