If you have co-slept, even once, you will probably relate to a few of these.
Two adults, or an adult and the wall, with the child sleeping horizontally between them. One adult gets the kicky feet and the other gets headbutts to the stomach.
Not a bird. This happens when you roll over and feed your nursling in a semi-awake daze and promptly fall back asleep. Nursling finishes and rolls over leaving your breast out in the cold for as long as it takes you to wake up.
When you find all the great things your kids leave in bed for you to discover when you roll on them at 2am. Like sand, tan bark, spiky dinosaur toys, cars and duplo.
When your child/ren will only sleep in the middle of the adults. Also see the "H".
The "I didn't sign up for this"
When you are puked on, wake up to a leaky poo nappy or, as once happened to me, you toilet learning toddler sits on you mistaking you for the toilet and wees all over you.
When you are woken by your kids talking in their sleep, usually hilarious.
Not a horses head on you pillow but your child's.
The child that sticks to you and is cuddled either into your back or in the crook of your arm.
The "bag of kittens"
When the child you sleep next to WON'T STOP MOVING even when they are sound asleep.
The "angels of the morning"
Older children who have their own beds and rooms but love to sneak in for a cuddle in the morning (I STILL do this when I stay with my parents)
The "happy campers"
the smug family who get more sleep, don't have to get out of bed and enjoy extra bonding and cuddles because they co-sleep.
