How long is you LO sleeping at night? Do you have to nurse them to sleep?

My daughter is 5 months and is still waking up almost every 1.5-2 hours for feedings. I literally have barely slept and it’s driving me nuts. She goes to be at 8:30. She was doing good and waking up only 2 times throughout the night at 11:30, then around 1 and would sleep until my husband would leave for work around 6am.

Last night she literally slept with my boob in her mouth and in my arms from 3am to 7am.

could this still be the 4m sleep regression?

Any advice?
