Sleep deprivation - help!

[Giraffe14]

Hi all. I have a 4 week old baby girl. We had an unexpected stay in NICU when she was born which resulted in 3 nights of zero sleep at all for me followed by the last 3 and a bit weeks of broken sleep due to the night feeds/nappy changes and mostly because of how loud she is at night. Grunting, straining, squealing. We have a 3 year old too who is up for the day at 7 and I think all this broken sleep has manifested into insomnia. I can't even seem to nap in the day no matter how exhausted I feel. I have been diagnosed with post natal anxiety but I can feel this escalating to PND and can see how much worse I get the more tired I am. I'm literally not getting nor have gotten more than 2 hours uninterrupted sleep in the last 4 weeks. Does anyone have any advice or ideas or even just a similar experience to share?? Tia

Congratulations!

Postnatal insomnia and PNA/PND certainly exist. Are you on medication for these. It might be that a prescription change is needed, might be worth a trip to your GP this week?

Babies sometimes are noisy. Maybe try a swaddle and dummy to see if it helps?

Assuming the baby is sleeping next to your bed, ear plugs and an eye mask may help you relax. You should still hear baby with ear plugs in if she's next to you, but it downs out background noise. White noise does similar.

Is your 3 year old napping? A cosleep nap with baby at the time toddler is napping may help.

Yes sounds normal. It's exhausting. I carried on with the nicu feeding routine when I got home and that helped. Also me and dh shared the night feeds for our twins he did 11pm-3am and I did 3am onwards.
From 4 months they slept through which helped.
Good luck
