All the rules change when you have twins. Trust me. Unless you are "supermom" or "superdad", a lot of things get marginalized compared to singles. Whether that is good or bad in the long term remains a subject of debate.

I'm not disagreeing with you, JayJay, but I do know a set of triplets that co-slept with their parents for the first few years of their lives.  As far as I know, it was mostly out of convenience, since their older child had a separate room.  All of the children are really cool, well-adjusted young adults now.

Our kids go to sleep in the bassinet next to the bed but after the first nighttime feeding they usually just stay in my bed for convenience.  When they hit about 6 months or so, I usually take the next 3 months and focus on keeping them in their own beds, which usually leads to them being in their own rooms shortly afterwards and reducing/stopping nighttime feedings.  Both of my girls slept WAY better in their own room than they did with me.  And I'm not someone who sleeps well when I have a child in bed with me - my "mommy spidey sense" keeps me partially alert and I don't get decent sleep.

I know co-sleeping for an extended period of time works for a lot of families, but my husband and I agree that our bedroom needs to remain "our" space.  I don't want to have to constantly go try and find hidden spots to make love with him, and I noticed my kids were just really dependent on me out of habit and not out of necessity.   When they were in our room they'd wake up and see ME there, and then want ME, instead of naturally learning to go back to sleep on their own.  I know also some kids who cosleep will naturally transition to their own beds, but many of them do not, and after seeing my nephew cosleep and pretty much destroy my brother's sex life, that wasn't something I wanted.  I am a wife FIRST, and mother SECOND.  To me that means making sure my marriage is in good shape, because a healthy happy marriage usually translates to healthy happy kids.  For us, that means keeping our private space private.

It's important to me to still be a very responsive parent, I hear my kids at night and even at ages 2 and 4 when my kids wake up and cry, I come to see them.  Some people probably think I'm nuts,  but I think that stemmed from when I was a working parent I had such limited time with them that I never really minded going in their rooms to comfort them, and then I'd go back in my room and I could sleep fine.  I don't know why, but I've always had a really hard time relaxing myself enough to fully let myself sleep when my kids were in the room.

We are into co-sleeping (and attachment parenting). Right when we came home from the hospital we put a sheepskin between our pillows, and made a little bed there for our newborn, in our bed. Since I am breastfeeding it is really convenient to have her so close, I don't have to get up, and usually we both drift back to sleep while she is still at the breast. Also, now (she's six months) when she has started to move a bit and roll around, if I wake up a bit, I can adjust the blanket for her and immediately go back to sleep.

When it comes to sex, it can be arranged for while she is fast asleep.

We have 2 daughters who are 5 and 2.5. Our older DD slept with us till she was 2.5 and I was pregnant enough that she weaned and we were both uncomfortable. She then moved to a toddler bed that was pushed next to ours. She didn't move to her own room till right before she turned 5. I had a huge issue sleeping without her right there for the first few months. Our youngest DD weaned a few months ago and still sleeps with us. She has a bed in her sister's room, but she's not ready to sleep there yet. My biggest issue with her is that she wants me to "hold" her ALL night long. I wake up pretty sore most mornings!
