Hi, glad you liked it! The dangle-master and baby swing are by Anna, here (http://an-nas.livejournal.com/4163.html).
Not sure about the toddler mats... I think the mesh might be the 1-tile pet bed from simwardrobe.com, but it must be a version that allows you to pick up recolors from the Maxis crib-- maybe check MTS? And I'm pretty sure the recolors came from GoS-- check this page (http://www.digitalperversion.net/gardenofshadows/index.php?board=57.0) for projects about kids/maternity, etc. The files start out "CO_maxiscrib-ataverablanket." Hope that helps!
