And you settle them in the cot, and they appear to go off to sleep, and you drift off to sleep too...
And then you wake up in the morning with a one-year-old in bed between you and your DH, and you don't know how he got there.
What are you meant to do when you actually have no recollection of putting your baby in bed with you?!
It's hardly behaviour I can change, is it?! Short of putting drawing pins on the floor between the cot and our bed, so I'm definitely awake when I get up...!
