1. Why do you cosleep?
It doesn't feel "right" to me to have a child further away from me, while I sleep, than I believe she is mature enough to handle comfortably without help from monitors, crib bars, gates, etc. For an infant, that means the only place is in bed next to dh and me. (They need a body, and close proximity in order for us to be able to waken to their signals before they become distressed.) At 3yo, my dd has no trouble navigating space alone at night, but she would still get scared and feel separated from the rest of the family if sleeping in a separate room.
I love how co-sleeping encourages night nursing *with little effort from me*. If I had to fully awaken and keep track, I would not have been able to nurse my dd many times a night during her first 2 years, and remain happy, well-rested, and unresentful. It has also facilitated our very laid back approach to sleep routines. Sometimes if dd1 is still not asleep by the time dh and I are ready for bed, we will get in bed together and read books. I realized recently that it can take as long as an hour before dd falls asleep this way, if she's not especially tired, but I don't notice or mind, because it's pleasant and cozy to snuggle in bed as a family and read. Oh, and once we realized that dd1 was certainly not going to need a separate bedroom within the next lease period, we were freed to move from a 2br apt (which we'd thought we needed for her) to a 1br, which is cheaper (and thus helps allow us to continue to stay/work at home) and easier to keep clean.
2. How long do you plan to cosleep? At what age do you think a child should be in their own bed?
Until a mutually agreeable (mostly child-led, but if guided by a clear insight I would nudge it along) time.
3. How many are sleeping in your bed now, what are their ages?
Dh (33), me (25), dd1 (3.5 years), and dd2 (3 weeks).
4. How big is your bed? And if you don't mind...what size are you and DP?
We have a queen and a twin, in opposite corners of our bedroom. About half the time, dd1 starts out the night in the twin, then comes into the queen with everyone else when she wakes up (could be middle of the night, or not until morning). Sometimes, dh wakes up early in the morning feeling squished, and moves into the twin to finish sleeping. Dh is pretty large, I am about average, in size. So yes, that is one cozy queen sized bed when we are all sleeping in it.
6. How has cosleeping changed your relationship with DP or has it?
Having children has changed our relationship, but I don't think co-sleeping per se has...
7. Ever had any problems with anyone getting hurt?
When dd1 had first learned to crawl, she crawled out of bed several times. Around the barriers I erected -- she was clearly determined and trying to learn how to crawl out, which she did by the end of the several times. She got some bumps on the head in the process, but nothing serious.
8. Do you and DP get a good night's sleep?
Yes. I don't remember waking up for most nursings, and am back asleep almost immediately after I have my newborn securely latched on (or after I take off her wet diaper and trek into the bathroom to see if she still wants to go in the sink and return to bed and replace the diaper and get her latched on
9. Do you use anything other than your bed? I mean, like a cosleeper or siderails?
When dd1 was younger (say, from crawling age to 21 months? I can't remember exactly), we had an old comforter folded in quarters, covered with a "crib" quilt, on the floor next to our bed. We sometimes put her down on that when we wanted to be intimate, then brought her back into bed with us. We never used siderails, but we did try to have something (e.g. a chair, a small table) blocking dd from rolling out of bed. Now we have our mattress on the floor, which is fun and cozy and helps us allow us to all fit comfortably (I feel comfortable being, or putting a kid, much closer to the edge -- I mean, we can hang off of it onto the floor, if we like).
