Baby blues and not sleeping

Hi mamas, my beautiful baby is now 8 days old. We had a relatively good birth, I was home 24 hours after she was born with my partner and day 3 hit me like a tonne of bricks it's also when my milk came in.

I don't know how to sleep, the advice sleep when the baby is sleeping doesn't work because all I do I listen for every sound and watch her breathing. She's either making little sounds or too quiet.

My partner has been so supportive and has been taking the night shift where I put headphones in and he takes care of her so I don't get distracted by all the little cooes or cries for nappy change but I still have trouble because the anxiety.

I cry every day which I know is normal at this point still.

When did it get easier and when did you manage to sleep a little better? (I'd even love 3 consecutive hours at this point)
