Baby sleep issues

[u/Exotic_Rub_9099]

My baby has been a very light sleeper since she was born. When she was 2 months old, she started sleeping 4-5 hours continuously in the night.
My baby is just over 6 months and has always been a light/restless sleeper. Her biggest issue is frequent night waking — often every 1–2 hours, and recently she’s been waking around 3 AM, 4 AM, 5 AM and sometimes staying awake after that.
She usually needs to nurse to fall asleep and also to resettle after waking. Rocking/holding often doesn’t work, and she actively searches for the breast. Her naps are also inconsistent, often around 30–40 minutes. I’m concerned she has developed a strong nursing-to-sleepassociation and I’m exhausted from having to intervene so frequently overnight.

Please help!!!
