Over the past two weeks, the girls have discovered how to climb up into their cribs by themselves. It's easiest for them to do it when the side of the crib is lowered, but they've also successfully done it a few times with the sides up, with the help of a step-stool. They get their feet up onto the mattress, between the crib rails, then swing a leg over the side and basically somersault into the bed. (Is this unsafe? It looks harmless to me, since they're they're only tumbling from a few inches away, onto a soft surface, but Alastair thinks they're going to break their necks. Please advise.)
In other gymnastic news, last weekend while staying over at Abu and Jacye's, Elsa climbed out of her Pack-n-Play at five in the morning. And today at naptime, when I went in to try to get the girls to settle down after 10 minutes of gabbing and gigging and bickering, Elsa was standing in Clio's crib. I don't know if she got all the way down from hers and climbed up into Clio's, or if she did a crib-to-crib transfer (their cribs are perpendicular to each other, in a corner), but either way -- it doesn't bode well.
Not that it's really a problem yet, per se. With the exception of Elsa's Pack-n-Play adventure and today's crib-hopping, the girls always stay in their cribs. But the thought of one of them trying to get out of their crib in the middle of the night and getting hurt is beginning to worry me a little. And I'm not crazy about the idea of them being able to get up and come into our room whenever they please, either. They've also lately shown a great interest in climbing up into Mommy and Daddy's bed and "sleeping" (not), all of which begs the question: is it time for us to move them to "big girl" beds?
I hear some parents say that as soon as they do the big transition, naps are history. Others say it isn't a problem. But given the girls' rather erratic napping habits these days -- Clio, especially -- I worry. On the other hand, for whatever reason, I'm kind of looking forward to moving beyond the cribs. I don't know why, really. Maybe I like the idea of being able to sit on the beds and kiss the little monkeys goodnight without having to do contortions. (Then, I guess we'd still use some kind of safety rail at first anyway...)
We could take an intermediate step to toddler beds, just so the girls don't feel overwhelmed by suddenly being in twin beds. On the other hand, unless I can get them very cheap / free, I don't particularly feel like buying something they'll outgrow in a year.
When did you / are you planning to bid the crib farewell? (For reference, Elsa and Clio are almost two and a half.) Any advice on how and when to make the switch? Pros, cons, etc.? Oh, and HAPPY MOTHER'S DAY all you fabulous mamas out there!

Look out -- here we come!
