Stormy given she hasn't already started trying to climb out it is highly likely she never will. Most of my friends have older or even adult dcs now, and from what they've told me toddlers are either climbers or they are not. My neighbour has a dd and a ds. Her dd was happy to stay in the cot, and then happy to stay in a bed. Her son climbed out of both. It's a personality thing.
Alba switching to a toddler bed is unsettling, so my advice is do it sooner rather than later and get the difficult bit over and done with as soon as possible. There is no way of avoiding chaos, just averting disaster. Remove anything from ds's bedroom that he could really hurt himself on - drawers he could pull on his head, side lights, that kind of thing. Either stair gate the stairs or his bedroom door, or if you don't have stair gates, lock his door, so he can't fall down the stairs. Put a mattress on the floor by the side of the bed just in case he climbs over the bed rails. Use an intercom so you know when he is up and about. Accept that for a good few nights he probably won't self settle if he wakes, he'll get up and try and find you.
Third night in a row of no sleep. Literally none. Not the toddle this time, acid reflux. I think I've reached the rather depressing point where babax is just too big for my small frame, and his butt is on my stomach. Been here before with the toddle, so at least I know what to expect. No sleep at all for the last month, and a huge sigh of relief when I hit the supposedly awful newborn days 
. Ah well, it'll all be worth it in the end, but right now what I need is a vertical cat nap.
