OP - and, sun. Since it is springtime already. Sunlight helps some people with depression. Certainly worth a try.

yellowted - Professor James J. McKenna is the leading US researcher on infant cosleeping. See Mother-Baby Behavioral Sleep Laboratory // University of Notre Dame for state of the art research. I imagine that those UK health authorities that attribute deaths to cosleeping make one or more of the following major mistakes: 1) claim causation where there is none 2) fail to separate the influence of confounding factors, such as second hand smoke exposure, babies' being placed on their stomachs, etc. There may be more issues with how they compile and process their statistics.

OP - you do not need to read that since your baby is already outside of the window of risk for SIDS.
