Not really an AIBU but not sure where else this belongs and could do with some support.
I've struggled with insomnia since I was pregnant with DTs (now almost 3), sometimes worse than others but in the last 18 months it mostly settled into a rhythm of getting off to sleep fine then waking around 4am unable to get back to sleep. That's been broadly manageable as long as I get to bed at a reasonable time.
I'm now 13 weeks pregnant with DC3 and starting to lose it a bit. DTs mostly sleep fairly well (7.30pm - around 6am most days) but I just can't sleep myself. I think I'm averaging 2-3 hours a night and its starting to take a toll. I work 4 days a week so DTs are in nursery 3 days a week and with DM 1 day but the evenings are relentless. I'm managing to get through work ok but I'm at the end of my tether by the time I get home to poor DTs and DH.
Has anyone else experienced anything similar or has any tips?
