Just for fun - as if you're on this page you are probably having problems getting your little ones to sleep. So I'll start:
You know you don't have a natural born sleeper when.....
Very occasionally you wake before your baby, and panic and rush into their room to check they are still alive
You realise your friend with a newborn is getting more sleep than you despite your baby being 10 months
Your friends babies (the same age as yours) have sleep regressions and are still getting more sleep than you
You have a mild addiction to baby sleep forums - just knowing there are others as sleep deprived as you makes it all seem so much better
You literally can't get through a day without sugar, and lots of it
Your main reason for wanting to give up breastfeeding is so that you can up your caffeine intake to required levels
