SLEEP REGRESSION

Okay so..

My LO is 3 months + 10 days and she is showing some serious signs of either a sleep regression or terrible growth spurt.

We are pretty lucky, she usually sleeps from 7:30pm - 5 or 6am each night and has been doing so since about 5 weeks old. She does have severe reflux and it’s always me rocking and calming her to sleep as she’s always in pain from this (She’s on medication etc so we are dealing with that).

My question is.. To those who have gone through the first sleep regression..

A) If she relies on her pacifier and being rocked to sleep in my arms now, does this mean she will need this each time she wakes up through the night through the sleep regression? We also swaddle as well.

B) Due to her reflux, she can’t cry it out.. We’ve tried and it makes her worse. I’ve tried gentle methods but she wont have that either. How do I get her to sleep on her own as apparently it’s important for her to learn to sleep independently during the sleep regression? Any advice?

She’s showing serious signs of a regression as she has been waking up at least 4 times a night and has trouble with her naps - completely out of character for her. I’ve even had to co-sleep a few times which I don’t want to do as she’s been in her own room since 5 weeks.

Any tips and tricks are greatly appreciated.
