My alter ego.
I may be clumsy and clang about and bump into things during the day, but once we tuck the boys into bed for the night, I turn into "NINJA MUM".
NINJA MUM slowly and stealthily creeps out of the room, along the hallway and down the stairs, even if it takes all night. She knows exactly where all the creaky floorboards are and deftly steps over them. She has super sensitive hearing and will respond immediately to moans and groans with a quick shush.
She has been known to crawl out of the room backwards, never taking her eyes off the cot, convinced that if she turned her back on the baby it would break the spell of sleep.
