We've been co-sleeping with my 1-year-old ever since she was born. We want to transition her to her crib now. Any tips?

I recommend putting her down for a nap in the crib during afternoons. This way, she won't be overwhelmed when it's time to transfer her there at night. Keeping the crib close to your bed also helps so you can easily get up and soothe her should she start crying.
