What sleeping arrangements do you have for your toddlers?

Baby just turned one and she used to sleep so well in her crib but will only co-sleep now due to separation anxiety. I love being close to her but my back is killing me from the constant C Curl and I miss sharing a bed with my husband at night.

So I’m curious: What kind of sleeping arrangements do you all have for your toddlers? Do you use a sidecar crib?
