anyone know if you can buy them with 2 baby units? i cant see any anywhere, well except the ones that are like 200quid with video and everything!! i'm really suprised they're not more common, its not as if its that uncommon to have 2 kids! the only other thing i can think of is to just buy two and either sort of link them some how, or have them on different channels and have two things with me all the time, which is a bit of an arse!!
