Hi,
I'm not sure if this was suggested before as I didnt come accross it while reading the forum.
I would personaly buy some wall stickers if you would make them (good quality that doesnt chip the paint when they get removed) with:
- note symbols
- Do to Do, Re to Re, etc
- the notes of a few popular songs on the clefs
Maybe one day the idea will be considered.
If they will be made, another suggestion would be to make a black and white version to stick it near the cot for a newborn to 6m old. And maybe diffrent sizes too.
