Wes is into everything now. If he can crawl to it, pull up on it, climb into or over it, put it into his mouth... you get the idea! Nothing is safe, he needs constant supervision:
I'm pretty sure this is what Dennis the Menace would have been like if the comic started earlier on in his life. And, to boot today he started making raspberry noises. Now not only is he into everything but he is "farting" his way from mess to mess!
