B.S.
I skipped buying a toddler bed and went for a twin with a side rail thing you slide under the mattress. It works great for me. As for sleeping on his own, I acted so excited about the big boy bed that he couldn't wait to try it out. Also, it took a week or so, but my son learned that nap time and bed time were non-negotiable by me taking him back to bed every time he got out. A great book is also "Healthy Sleep habits, Happy Child"... I highly recommend it.
Good luck!
