As a strong proponent of cosleeping, I think that is the very best solution to any and all "sleep problems". Lie down with him till he falls asleep, or nurse him to sleep, and then you can get up, and join him later. He is not old enough to fall asleep on his own, although babies can be "taught" to by letting them cry it out. But what they are really learning is that you are not there for them, and the world is not a safe place, and they have to take care of themselves. If you are there for him while he is young and needs you, he will feel safe and independent when he is developmentally ready. Please don't let him cry it out! He is right now in the separation anxiety stage, and it is a good sign that he is well attached to you that he wants to be with you. He needs to know you are there for him. You could move the crib next to your bed as a cosleeper arrangement, so you could lie with him or nurse him to sleep and then roll back over into your bed. It is absolutely normal and developmentally important for babies this age to want to be close to you and to wake up for comfort from you several times a night. I have raised two wonderful independent secure loving children this way, and they now have their own babies and cosleep with them. It really really works!
