With my DS, he slept with me almost from the beginning. I tried to get him to sleep in the crib, but I think he was so used to sleeping in our room, he would NOT sleep in the crib and I needed sleep, so he slept with me. DD1 did not sleep with me until she was about 1 year old...but especially around 2-3 when I was going through my divorce. After they were older, I had them sleep in their beds, but they ended up in my bed sometime during the night. It wasn't until I got remarried, 4 yrs ago, that they started staying in their beds. Now DD2, I was anal about her sleeping in her crib...well, my ex-hub would about pee his pants because he wanted quiet and sleep so she started out sleeping in the living room with me, but in her car seat....then once he moved out, she went to the crib and was my absolute best sleeper of them all....up until she figured out how to climb out of the crib at about 1 year old. She would NOT stay in the crib and would cry and cry and cry....so she now sleeps with me. I am currently cleaning out the room and putting a toddler bed in for her to sleep.
I will say, that I would not trade any of the sleeping and cuddling with my kids for the anything. It made all of us feel so close together....
