hello I didn't see this on Friday, sorry!
and now I can't remember what Friday was like
today was lots more of the ear-piercing shrieks though, and a hilarious half-hour where I dangled a toy, he gasped with delight (the Most Beautiful Thing He'd Ever Seen!), took it, dropped it, then shrieked.
So I picked him up and he put his head down on my shoulder, fingers in mouth. Apparently all that shrieking and toy-dropping means, "ready for a nap now, mum".
on the other hand, we also had half an hour of him lying between us on the bed, giggling his fool head off while first dh and then I said "beep". Strange little people, aren't they?
