and had only 2 1/2hrs sleep since 9am this morning. I'm about to bath him and start the bedtime routine (he goes down at 8) but I'm really hoping that this isn't a sign of things to come - he's not quite 6 months old yet and by the time he goes down he'll have been awake for 5hrs!
I thought he'd be getting grumpy by now - but no he's giggling away at DS1 and DS2. I hope this isn't a sign of things to come.....
