Listening in too.....
We are in the process of transitioning our 2.5 yo into the BGB. The only thing that triggered the move for us was that my husband wanted to take over one of our guest bedrooms and turn it into a work out room, so he wanted the bed that was in there out, hence it is now hers.
We moved it up into her room 2 weeks ago. I took her with me and let her pick out (from 2 acceptable alternatives) the bedding. For the past two weeks, we have been reading our bedtime stories in it. In fact, if I lay down on it, DD shouts "No, jammies and stories only". I just bought safety rails yesterday and plan on installing them tomorrow. Then, I am going to start with naps and do just naps in it for a few weeks before nights, assuming all goes well.
Good luck to you
