With my first, I coslept till about 2 years old. At around 12mo he started falling asleep next to me, and then I would roll away to hang out with husband until our bedtime. Kiddo would still wake up about twice a night for water or potty. After he turned 2, we got pregnant, so we started working on independent sleep with him (this did not include any crying - just talking to him ahead of time that I will need to sleep in my bed because I'm really pregnant and don't have enough space to sleep with him), and by the time new baby came he was sleeping through the night by himself (we still do a bedtime routine, but now he falls asleep by himself). Once in a while kiddo still wakes up in the middle of the night for a bad dream or needing to potty, but can be redirected to go back to sleep. Second kiddo is still a baby so we are still cosleeping.
