It's soooooooo infuriating isn't it? Especially when they dint seem to realize that if they left the baby to sleep they would get more attention themselves!
Seren's trick is to stay in bed until Willow is asleep and then get up for a wee. She clicks the light on loudly, leaves the bathroom door open and drags her step across the bathroom floor just to make sure Willow is awake.
