Son flushed toothbrush down the toilet

It might have went down, depending on the toilet's trap size and shape.
Continue using the toilet. If the brush is still in the trap, the next big poop 'clean up' (it'll be the toilet paper not the actual poop) that will let you know. The best solution then is to remove the toilet and back flush the trap. If it did make its way down further down the pipe, there's no guarantee it won't get hung up somewhere else, but chances are it'll be fished out at the treatment plant.

Glad it worked out for you! Thanks for replying.
As engineered said, you don't need to remove your initial post. Trust me, you aren't the first nor the last parent that had a little one flush something inappropriate down the toilet. Leaving your question up may help someone in the future.
If you don't want to receive any more replies, you can change it in your settings (it's available in the email, if you set up email relies).

Cheers.
