At 3 1/2 M finally got a big boy bed. He never climbed out of his bed and since there are no Gilbert babies joining us soon, we put it off for as long as our consciences allowed. But we finally decided now that he's potty trained he is probably ready for this next step. He has done really well, he's only fallen out 1 time and snuck downstairs after bed time 1 time. I have had to alarm clock train him because the new freedom has allowed him to get out of bed before 7am, which is an absolutely no-go for me. He has been great about waiting for the alarm to go off since I instituted that policy. My baby really is a big boy.
