My neighbour (terraced houses) who I am really close to since lockdown and having her baby in February makes a strange ululating sound to calm her very colicky, refluxy baby, and I can hear it through the thinnish walls. It is similar to when I used to hoover to calm my colicky newborn. She makes a high pitched "lololololololo" sound whenever he cries to sort of drown him out and calm him. It clearly works as he stops crying.
Only now he is 5 months old, and still waking and crying frequently, only the crying is getting louder and so is the noise she makes. Add to this the fact that it is hot and her baby's room is next to our bedroom with both sets of windows open for coolness.
Now I am all for people calming a crying baby, as that is a terrible sound on its own, but it is getting to the point that we can barely watch tv in the evenings or go to sleep and are frequently woken at all hours by this high pitched screeching.
And to be abundantly clear, she is white and English, as are her partner, parents and grandparents. The sound she makes is exactly like I have heard at an Indian friend's wedding party, but it is clearly not cultural, just a fluke that calms her baby.
AIBU to ask her to figure out a quieter way to calm her baby, at least between 10 and 6 or 7?
I found a youtube video which is exactly the sound for a better idea of the sound.
