Hi Nicole, so sorry sleep is few and far between for you these days! I promise it WILL get better, but it never feels that way when you are in the midst of it. I think you are doing a great job of trying to find a practical and safe sleep solution for your daughter. The biggest piece of advice I can give is to avoid the sleeping on the couch arrangement as you mentioned- this really is a huge SIDS risk and despite many moms thinking they are aware, when you are exhausted and finally fall into a deep sleep, suffocation and SIDS can result. Moses baskets with firm bottoms can be great (and portable!). It sounds like you already are aware that co-sleeping with your mattress especially is not a safe option, given how not firm it is. Have you considered a co-sleeper such as this?:
They make a bunch (including smaller ones) and are great in that they are a safe sleep environment that are at the height of your bed – great for nighttime feedings! Whatever you choose doesn’t have to be expensive either – just safe! I love what moms do in Finland regarding where their babies sleep, too – check out this box idea! http://www.bbc.com/news/magazine-22751415
I agree with everything Dr Lincoln has recommended!
Thanks for the advice! I purchased an in-bed cosleeper that my husband will be picking up from the store tomorrow. For the moment, I’ve been sleeping with her on that firm twin mattress on the floor. Also not ideal, I know, but better for both of us than the couch. When I get the cosleeper I’ll probably first try it out on that same mattress, and if it works well, move to our king bed. And if THAT works I might try putting it in her pack-n-play next to the bed to try to transition her to sleeping in just the pack-n-play.
