Got Milk?

Isn't this picture of Weston cute playing in some spilled milk? He just looks so innocent. Our old sippy cups that we got for free from the Safety First company are just not doing the job anymore now that the kids like to throw them down. The lids keep popping off, so we've switched to the Playtex sippy cups and they're working fine, but all sippy cups leak, no matter what the packaging says.
