If you'd like to post the kids audiograms we can help you understand their specific hearing loss (and what they can and can't hear).
How are you communicating with them, and they with each other?
If you aren't already doing so, I'd recommend learning and using Sign Language (in addition to speech).
In case you are concerned that signing might "hurt their speech", take comfort that it's actally been proven over and over again that both hearing and hoh/deaf children atually benefit from being in a ASL and English environment and develop BETTER language skills than they would if they didn't have ASL.
