My wife and I coslept (and often still cosleep) with both of our children. They both sleep through the night without issue. Our oldest goes to sleep early and will insist on going to sleep when she feels tired and will wake up with me in the morning. Our youngest fights sleep until exhaustion and prefers to sleep in (until 9-10am if allowed). They have been raised exactly the same way. We take way too much credit for our children's sleep habits.
