To co-sleep or not to co-sleep?

That's not a very original nor accurate title because we have 100% chosen to co-sleep from the very get-go. Una is now almost 14 months and she has slept in our bed until now. It's been a great way for her and I to connect after I have been at work all day and it's been convenient for nursing. As we are now wrapping up the night buffet and I'm not away at work all day, I was thinking it was time to transition her into her own bed. I didn't want to go with a "cold turkey" strategy and sleep train her by letting her cry it out. I'm more interested in a slow progression from our bed to her own bed where she can have time to get used to it one small step at a time. Just like we have cut down on nursing one meal at a time - and it hasn't been a linear process by any means.
So I bought a crib where one side comes off and last night she slept in it - next to me, but on her own. She wakes up several times at night and sometime around 2 am she came all the way over and slept next to me. All she had to do was crawl. Next step (when we feel ready), will be to put the side back on the crib and move it an inch or two from our bed. And next step after that will be to move her in her own room - that is, when we actually build the studio and have a room to put her in.
