My baby is 9 months almost and still waking up every couple hours...thnk he's gonna be around one bfor sleeping threw the night. every baby is different

My baby has been sleeping pretty much through the night since 2.5 months

I'm sorry I just saw the when but whenever they are ready to. My daughter did since she was born

Whenever baby does it. Some do it from birth, some at 6 months, some not until 1 year, etc

Yes as long as they are over their birth weight.
