I need some advice.. I’m absolutely exhausted.

I used to have a great sleeper who slept 9-12 hours straight starting from 7 weeks, then she turned 4 months and the regression hit and she started waking up 1-3 times a night to nurse.. ever since then we have dropped down to 1 or 2 night wakings around 3-4am then back to sleep until 8.. this was fine with me.

Well, we just moved 4 days ago and she is now in her own room.. it’s been a nightmare. She’s up almost every 2 hours and won’t go back to sleep without nursing .. she is sleep trained, she puts herself to sleep for every nap and every night, she knows how to put herself back to sleep but it has become a habit of needing to nurse in the middle of the night. I have no idea how to go about this, I’m so exhausted in the middle of the night that I just nurse her then put her back down cause I don’t have the energy to rock her or listen to her cry. She has 5 teeth and is cutting her 6th one right now so I don’t know if that has anything to do with it.. but I just need some help 😭 she is 9 months today and I am going to start offering her formula to start the weaning process at 10 months so she will be weaned by her 1st birthday, hopefully that will help.

Sorry this is so long lol
