any one else? sleep regression?

my little man is about to turn 6 months on Saturday and lately he's been waking up at night and screaming bloody murder he usually wakes up once a night for a bottle anyway crazy.

I really don't want him getting in the habit of more bottles at night but he screams until he loses his voice and still nothing else works!

I'm assuming this is some kind of sleep regression anybody have any tips on how they were able to calm their baby down without a bottle.

we've tried rocking pacifier rubbing his back singing to him sound machine playing music.
