DS's still pulses! LOL. And coz he has spikey hair, you can see it!! His has always been quite visible and a little sunken.. I've never really worried about the dehydration thing, coz he's had NO problems giving me wet nappies to change! hehe.

Bit of a sidetrack - but does anyone know when it closes up? I've read it's a couple of years.. but then I've also heard it doesn't 'really' close up until the teen years! (might be similar to the bones in your wrist that don't join up until you've finished growing).
