Short story - my parents are deaf and are sleeping over baby sitting at my place in a fortnight. Their house is set up with the flashing lights so they can tell if the baby is crying overnight.

Google tells me that deaf people often use vibrating baby monitors. Mum can chuck it under her pillow (so she can wake Dad who does the night shift!). I'm wondering if anyone can recommend a model that has this feature? I'd prefer to have one that has two baby units as DS2 is still in our room whilst DS1 is in his own room.

Help?
