Dd2 was born 12 days ago (ELCS), and for the past few nights, I've been waking up in the early hours drenched in sweat. A quick google suggests that this is to do with hormone levels returning to normal. I'm exclusively breast feeding. Has anyone else had this, and is there anything I can do about it? It's driving me mad, as if having a newborn wasn't enough to disrupt my sleep! Not sure if it's relevant, but I developed an under active thyroid during pregnancy, & am still on thyroxine, to be reviewed at 6 weeks. I intend to ask my obstetrician about this, but he's currently away, & I would really appreciate any advice in the meantime.
