Mine is not. My first DS didn't for ages either (14 months before he gave us a full night's sleep. Then we got six weeks to restock on sleep before DD arrived, eek). I don't seem to produce children that like to sleep. And I'm fed up of hearing about everyone else's cherubs who are sleeping through, just like that.
I need to hear from fellow mumsnetters who are sleep deprived and grumpy just like me. It might just cheer me up enough to get me through the endless coughs, colds and tummy bugs we're also dealing with.
Let's burn the midnight oil together, ladies. (And 3am, 5am, 6am...) Remind me I'm not the only one. PLEASE.
