Nanit for deaf parents

I am deaf and my husband is hearing. We had hoped that the app notifications that could be synced to my iPhone would push to my Fitbit and vibrate when my baby cries/wakes up. Unfortunately, the vibrations are pretty minimal in length and won’t wake me up successfully.

I’m wondering if anyone has found a way of syncing something like a bed shaker or another device with their Nanit to ensure the message is received.
