Keep up with the water changes, and skip food for a couple of days. Your little goldie will be just fine. I would suggest changing water twice a day, that way you can get rid of the maximum amount of
ammonia with the least stress to the fishie.
I don't have any kids, but my Mom had 9 (I'm #8). So there are lots of nieces and nephews and grand nieces and grand nephews that come and want to play with Aunt Gremlin's toys and fish and birdies and doggie and "we have to feed the fishies cuz they are hungry". And of course the "I want to pick this flower cuz it is sooo pretty" as they pull up the entire plant... and then there is the ball and frisbee and other assorted toys that wind up in the garden, in the pond, on top of the bird cage, inside toys outside, dirty outside toys inside on the carpet. Yes, children can be a pain. Then they go home.
