We have a spare bedroom that turns into my playroom sometimes, I have a tv on the wall and (2) rubber made tubs in the corner, one has lego's the other has a bunch of toys.
When we have time to play my girlfriend will usually go into the room and turn of the tv (satellite) and switch it to a kids tv show or cartoons, then I come in and start playing, usually she'll ask me to build her something out of legos, the mixture of background noise from the tv and concentrating on building the perfect lego house or truck gets me in little space in no time, I sometimes end up sticking my paci in my mouth then forgetting that its even there because I get so absorbed. Def love it.
* Also helps if I get a diaper change in the room, between the smell of the baby lotion and baby powder after the change the scent lingers and its makes the room feel so comfy.
