Input: My eldest son (8yo) just got back from a friends party and was visibly upset, when asked what was wrong he said some of the other kids were pushing him around and jumping on him on the bounce house, another kid grabbed him by the neck and punched him. 

He said he told he the mother of the birthday boy and she brushed it off and sent him back out to play. 

I messaged the mother of the birthday boy and she claims nothing happened (though I tend to doubt her honesty based on prior experience with her).

He doesn't have a history of telling tales and I have no reason not to believe him.

I also messaged the mother of the boy who punched him and she said, "It's a kids party and neither of us were there at the time to witness it."

I know my son is fairly quiet and not into horseplay so AITA for being so upset.
