I have a climber. I've gone through every kind of baby gate imaginable - even the extra tall ones with verticle bars only. He's managed to figure out a way to get over all of them. I've caught him in the act a few times & although he's tiny, it's pretty amazing how strong he is! Not to mention soooo cute
I eventually decided to let him roam. He's potty trained now & it breaks my heart seeing him get all worked up trying to climb the gates.
