The amount of times I have heard 'Anyone who says that their child sleeps 12 hours a night is a liar' is really starting to get on my nerves...
My 10mo DOES sleep 12 hours a night. She also eats most foods, mostly plays well with other children and is generally quite happy. I know other people who have babies who sleep 12 hours. It can happen. I do not claim that this is due to any brilliant parenting, some of us are just lucky. We are not, however, liars!
Nothing wrong with praying for a bit of luck, or for appreciating it while it lasts. She will probably be the world's worst teenager.
Disclaimer: Do not brag about the sleep, but do tell people if they ask. Sorry if you are a sleep deprived mum reading this, your child might be an easy toddler...
