Sorry to hear of continued rubbish sleep. We're the same here, two hours awake and seemingly in pain in the middle of the night.
GT my DH's auntie had twins then ten months later had her third baby. She swears it's easier on the body if you get pregnant again within a year because everything is still 'loose' from the last baby.
Luis my dad had a nervous breakdown aged 44. He had to retire, my mum went back to work and he never worked again. That is apart from raising three children from when we were 10, 7 and 2. He was the one who looked after me when I was sick. He was the one who read me bedtime stories. He was the one that took me to school, and the dentist, and music lessons. He made my school lunches and my dinner every day. I know he missed being the breadwinner and he missed working life as well. But a quitter he ain't. You feel bad now because things are so hard, especially with difficult nights. But J is going to amaze you with what he gets up to as time goes by. And the nights will get easier. I am going to have to give you a hefty for feeling guilty over genetics, that's one thing none of us can have any influence over.
Lily I'm in the OU club too. Two exams in June and I am bricking it. My brain doesn't work anymore, how am I supposed to understand maths?
I would see the GP Chunky, some ear drops may be all that's needed.
