Need some help and perspective

Our girl is 20wks. She is still in Leap 4 and experiencing sleep regression.

It’s been very difficult getting her to sleep at night and then she wakes up several times per night. This has been going on for a month.

Then last night, every time we put her down in her bed, she woke up crying. When we picked her up she’d fall asleep almost instantly. This continues for nearly 2 hours till we finally decided to cosleep.

We’ve all been sleeping terribly last few nights.

In bed with us, she only woke up once. So now I’m wondering if the problem is Leap 4 clinginess. I don’t know what to do. The thing is, we don’t want to cosleep. It’s just not for us...we don’t want this to become a habit.

Will this pass?

Is this Leap 4? Sleep regression?

What can we do to avoid cosleeping and still get her to sleep well?

She’s EBF...

Any advice and perspective welcome
