This is how I walked into Mason's nursery this morning. Busted! Ever since Mason started crawling a few weeks ago he has improved his core strength so much that he's able to sit unassisted and is now reaching for anything in his grasp. Including his poor mobile animals who happily dangled above him while he slept. I disassembled the mobile and turned it into a 'music box'. As I look at Mason and how tall he is sitting and wonder if he realizes that with a bit of strength, he can easily grab the top of the crib and pull himself up. I'm hoping that won't be for a while or else I'm going to have to drop the mattress to the "toddler" level! and we all know how much my back is going to appreciate that! What a monkey!
