I can only speak about what worked for us. I wanted to keep our bed sacred since it's the only place we can spend time together alone. Plus, I read alot about the dangers of rolling over or the child falling off. So, for us, we didn't want to do it. With that being said, we don't make our son (now 18-months-old) to "cry it out", especially in the middle of the night. We bought a futon and if need be, one of us will lay with him in that. We also wouldn't take him out of his crib right away. We'd offer him water (sometimes he wakes up and is thirsty- I know I get the same way.), check if he needed a diaper change (if so, we'd take him to get it changed since he won't sleep if he's uncomfortable, plus it avoids morning leaks) or give him his pacifier back (sometimes he will wake up if it falls out) and then walk away. He usually just lays back down. Granted, we understand every child is different and this may not work for you but it works for us.
He's a happy and healthy baby and pretty independent. I talked to one mom I work with who has 4 children ranging in age from 3-11 and she says they've always slept with her and still do. My question was when do they spend time alone together? But then I realized they had 4 kids so they must've found the time. Basically, do some research on the pros and cons and decide what works for you and your family. For us, we won't do it. Take care!
