The under floor sound deadener sounds good. Do you think it would make a difference only applied to her room or would we have to do the whole house? Her room has only a small under floor access height clearance and the rest of the house can't be accessed unless we rip the floor up

We have drapes but they are pretty light weight so not that effective. going to look for heavier ones after we fork out for a couch!

Thanks for the reply and info.
