Yes she will!

My DD is the same. I feel bad because I feel like it's my fault too. She was pretty good at around 2 months then at 4 months it went downhill & I didn't try hard enough. Just did what was easiest. But then does "trying harder" then lead "controlled crying"? I don't want to do that so I keep going. DD spends half the night in my bed.

Having said that, my DS was the same as well and he now sleeps through from 8pm to 6am (ish) every night. He wakes maybe once a week if that & usually resettles after a quick cuddle or drink of water.

I keep reminding myself how much DS has improved to get through the these months with DD.

Don't be too hard on yourself.
