CoSleeping/bed sharing mamas - Lots of questions and would love to hear about your real life experience!

Pros/Cons of cosleeping for you? Where do your babies fall asleep? If they fall asleep in their crib, at what point do you bring them in with you?

We are currently cosleeping for part of the night. LO goes to sleep in his crib but comes in with us around 11pm. We are trying to decide if we want to make more of an effort to get him spending the night in his crib or continue to cosleep. LO is 7mo old and nis nursing 3ish times per night.
