Hi FF
In my experience, being submissive is something that always stays in your heart, but sometimes doesnt stay in your head on a day to day level.....this is surely natural, especially since you have quite recently become a Mum, it puts a whole new slant on life. i don't have children, but i do know that occasionally 'life' seems to get in the way of a D/s relationship, not only literally in pratical terms, but mentally as well.
Although i think you could consider physical things such as the collar etc, i think i would probably most concur with Nikka's suggestion in terms of atempting to re-focus on your submissive nature, most notably, obviously, towards TG. Also, although i agree that you should relax, i have always found that re-focusing on being sub is something that requires some degree of effort on my part...yes, of course relax and let things flow a bit (you cant obviously 'force' the issue with yourself) but getting the submissive side of you back in to focus both in psychological and literal terms does require some effort.
Anyway, that's me done...let us know how it goes hun.
