Hi I'm currently 40+3 weeks pregnant with our second daughter so basically ready to drop! The issue at the moment is with DD1 who will be 3 years old in a few weeks......
She has never been a great sleeper but improved about 6 months ago when she dropped her daytime nap and moved into a toddler bed. Still not 100% reliable sleeper but a hell of a lot better..... until the last few weeks....
She goes to bed at 7/7:30pm and falls asleep fine after her usual bedtime routine, but wakes up usually about 10pm and then we have HOURS of messing around, crying, stalling going back to bed, being naughty in her room etc.
My husband tries to help but all she ever wants is me and screams 'my mummy my mummy' constantly until I go in to her but I still can't settle her. She won't say why she's awake or what the matter is, I think a lot of it is attention seeking (which she gets plenty of during the day, particularly since I started Mat leave and am always with her).
Tonight she was awake from 10pm-3pm 
It is doing my head in, not only as I'm shattered as well and massively pregnant, but it is taking all the joy out of expecting another LO. All I can think about is how hard life is going to be. My husband works 2 weeks of day shifts followed by 2 weeks of night shifts so every other fortnight I will be having to deal with both girls on my own and I'm petrified how I'm going to cope.
I'm already starting to feel extremely anxious, depressed and terribly guilty that this baby seems more like an added burden at the moment and that I am starting to feel resentful to my 3yo.
I suppose I just want to know if anyone else has experienced similar and has any idea what might help my eldest daughter sleep better, or how I am supposed to cope on my own at night in the meantime due to toddler night tantrums and breastfeeding a newborn? X
