Hi T.,
Yes, I've done it enough now to be considered an "expert" I think. :)
We are sharing our family bed with a nursing toddler and a nursing infant...and this has been our usual pattern with all of our 7 babies. That's right, I've been doing this double co-sleeping thing for almost 15 years...and I'm living proof that it works. We love it!
My research (both book research and living research on real life children) has taught me that all babies 3 years and under have a natural, deep-rooted need to be with their mommies during the night. Now some babies have an "interruption" in their development which interferes with the natural rhythm of cosleeping (this could be a trauma of some sort or a premature weaning or other challenge) and they may not fit this mold. But on average, babies thrive with their mommies beside them, becoming more secure, confident, and independent in the daytime and later at night as well. My older kids couldn't be more independent and confident than they are, and now the oldest ones are happy, mature, compassionate teenagers. I'm so pleased!
So, all this is to say...follow your heart and invest in your babies! Sure there is some sacrifice and selflessness involved, but the pros so outweigh the cons (just like breastfeeding!) and the rewards are huge!
There are lots of good resources online and in the bookstore to help with the Art of Cosleeping. It's also great to get together with other like-minded moms to share mutual support and encouragement.
Give yourself permission to relax and get used to having little ones in close proximity at night. This seems to be very much a mental exercise. Full acceptance leads to deeper relaxation which leads to better sleep. (My hubby and I don't even notice movement and noises anymore...I've trained myself to sleep through it all!) :) When you really believe in what you're doing (I wish I had time to list the 20+ benefits of cosleeping!) it helps you embrace the experience and find deep fulfillment in it.
Here's my favorite website: http://www.gentlechristianmothers.com/
with tons of support and encouragement!
And 2 of the best books I know of are: Dr. Sears' The Baby Book and Sheila Kippley's Breastfeeding and Natural Child Spacing (http://www.amazon.com/Breastfeeding-Natural-Child-Spacing.... These 2 books changed my life and made me the joyful mommy I am today!
Congratulations & Best wishes! You'll be in my prayers. :)
