Try baby sleep music

I had problems with my son sleeping when he was young but sleep music worked a treat.

Glad it worked for you. Though keep in mind that approach may not survive regressions

Since I was a kid, I've let him listen to classical music. So when he was born he could sleep soundly when I played those songs.

I wrote a load of calm piano music to help my daughter sleep. Hopefully it might help your little one too!
