I know how you feel! I just went through this with my 2 year old twin boys. Wow, what a shock to my system! I didn't know what happened to my "good sleepers" when we converted their cribs to toddler beds. What worked for me? Honestly, I just kept putting both of them back in their beds over, and over, and over again. It was a little stressful...no--very stressful, but it really did work. I also removed their bookshelf and a few other "distractions." This helped us a lot. We put safety locks on the dresser drawers because they were emptying the drawers. My husband and I worked "smarter" rather than harder and luckily they both slept in their new beds after a week or so. The "rule" is they stay in bed until my husband or I get them. Oh yeah, we also put a child safety handle on the bedroom door. We won't keep it on there forever, but it does help keep them in their room. Hope this helps. The last thing that really helped me was a nice glass of wine right before bedtime--just kidding :-)
