Hold tight to the precious memory of your three year old snaking her soft little arms around your neck and whispering “will you lie down in my bed with me mummy? I love you so much and we’re best friends”. Hold particularly tight to that precious memory 40 minutes later at 4.30am as you cling to the edge of a single bed, taking erratic kicks to your kidneys, with a stuffed monkey wedged under your chin, finding yourself saying things like “stop wriggling and go to sleep! Did you seriously just wipe a booger on me?! Don’t DO that!”
