Baby Won't Stop Babbling

Ai

Help! My 7 month old babbles day and night. When she has a nighttime wake up, she will be fed or comforted and will talk to herself VERY loudly, basically screaming for like 45 mins after. She will not take a pacifier. I have tried all of the usual night waking techniques. Don't engage with them, no eye contact during night time waking. None of it works. I have another child that is 2.5 years old and she keeps her awake as well as us. My first child babbled but not as frequently or loudly. I know it is an important milestone but I just need sleep! Any advice is appreciated.
