It's the same for both of us. She used to settle for him at night and not me. Now we both can cuddle her to sleep, then the second she touches the cot she starts. No matter how deep her sleep.
I try and leave her but i end up giving in within a couple of minutes as the screams are unbearable. I'll put her straight in bed with me and cuddle her and she sleeps instantly!
The passed couple of nights she's gone to bed wide awake and will go to sleep herself after 10 minutes, no crying. But at 4am it's hell again.
So it is getting better. We just need to crack the early hours screams.
