Right now my favorite time is any time my husband is here to take care of me, so right now I don't get a lot of that.
But during more normal circumstances, getting ready for bed, and "pretending" that I don't want to wear (sometimes complete with pantsless chase through the house) and then settling down to get diapered up, followed by big snuggles and sleeping butt-to-butt with my husband is my favorite time.
