I tried listening to it both claimed ways and I could hear both as plausible. I don’t think it can be determined for sure from the audio alone, might need testimony from those present.

But yeah, either way, it’s someone screaming at a baby/toddler, which is vile behavior. Like ffs, the parent is right there, if you really have a legitimate issue with them, you can talk to the parent, leave the little one out of it. They are too young to even understand what is happening, much less deal with it. So cowardly.
