I totally agree too! No toys in the bathroom.

However, I know parents who encourage toy play in the bathroom. It draws out the length of time they'll sit on the potty and wait to go. IMO I don't think this assists them in training... it's just a matter of fact... oh look, I sat here long enough I pee'd.

I think if it's something that is creating that big of an issue at daycare I would ask the parents to jump on board. This may be one that they think is ok and won't be willing to break at home though.

Make sure you focus on the reason behind it so they understand and buy into it.

All the best! Don't stress out, your job isn't to train the boy, your job is to support the training that's being done by his parent.s
