Six months into my pregnancy and I started having more difficulty in sleeping.  It takes me about 30 minutes to find a comfortable sleeping position and as soon as I feel sleepy, I need to be up again for bladder break!  I’m glad that we have a mattress that’s really good for my back, as it is not too soft and not too hard.  Although I have no idea whether a sleep number bed will be more helpful, I’m content with the comfort our current bed gives me.
