i have a portacot set up in the lounge room (so Anneliese can have tummy time without the boys jumping all over her!) and i usually jsut put her in there. When the boys were little, they would generally just follow me, and would either sit just outside the door and waitfor me, or in the case of showering, they would just come in and sit on the floor (i'd put a couple of toys on the ground for them.)
