Hello Sheeberi,
I was co-sleeping with my son from birth to 3 months old. After 3 months I put him in a bassinet next to my bed and he slept there until he was 4 months old. From there I moved him into his crib in his own room. The first few nights of the adjustment was hard even at the early age. He cried for 3 nights. Then the fourth night I out him down he yelled onced and rolled over to fall asleep on his own. I am so thankful that I did this early one because I can't imagine how long he would cry now, now that he is older when I leave him. This also helped him sleep through the night because he soothe himself to sleep every night and when he wakes in the middle of the night he did the same.
I would recommend, moving them to their own room with their own crib ASAP. One year olds can sleep alone and plus you need some alone time with you husband.

Have a bed time routine. Do the same thing every night and eventually they will get tired and fall asleep in their own beds. It will be hard the first couple of nights and there will be crying but trust me it will all be worth it.

There are also many books out there that many parents reccomended to me such as "Baby Wise" to help baby sleep through the night and on their own.
