Thanks for your concern guys. Well I feel a bit silly now...She had a really good feed at 10pm, followed by a big long cuddle (for my benifit not hers LOL) She slept perfectly until 4am, had a feed then came into bed with me at 6.30am and fed & played. Just like every other morning. She is happy and smiley & I feel like a goose 8-[ But I'm just glad she is OK. You might be right Tracey, she probably got overtired. She just doesnt normally sleep much at all through the day, maybe this is a bit of a transition time?....

Thanks again girls for all your help!
