How should this be punctuated ?

[Asmallrole]

Goodnight my darling I love you sleep well and I'll see you soon

Goodnight,my darling. I love you, sleep well and I'll see you soon.

Goodnight my darling, I love you. Sleep well and I'll see you soon.

Is how I'd put it, but there are no doubt other equally valid ways.

Goodnight, my darling. I love you. Sleep well, and I’ll see you soon.

Thanks all
