Crib tents only delay the inevitable. And "wait until she figures out how to unzip the tent" is just asking for her to get entangled in the tent and possibly choked by it or caught on it when she tries to get out around, under or over the tent.
If a child can get out of the crib, tent or no tent, it's time to move to a bed, toddler bed, mattress on the floor. Try this: Put up the side of the crib. Really look at the distance from the top of the raised crib rail to the floor. Picture your small child falling that distance. Onto her head. It could be fatal. That 's a long way down for small kids. My friends 18-month-old broke her arm the first time she climbed out of the crib. I've posted that so many times here but so many moms just don't want to handle the transition to a life outside the crib. Yes, you'll have to teach her new skills to stay in her room and in her bed, and that will be a tedious and frustrating period, but it must be done sometime so why not now -- she's already saying she's ready to get out and feels trapped by the tent.
