Engineer in training

Tucker was in the habit of chewing his sippy cups so that they'd leak and he could walk around the house pouring his drink out. To fix the problem, we bought him this (pricey) Camelbak bottle that we thought was indestructible.

 

And it's done a great job for about a month. 

However, today, Tucker yet again outsmarted his parents:

It's a good thing he's so cute, or I'd have to be mad.

Side note: At his 18 month check-up today, Tucker was 29 lbs, 10 oz and 34.5 inches tall. Big boy!
