Thank you for posting as we are looking for one for 2 kids as well. Right now we have the Summer Infant Slim & Secure (I think thats the name) and we've never had a problem with it. I like that it has a clip which ive used several times, and it holds a charge really well. The only thing I don't like is I'd love to have one that works on my iphone so if we hang out with the neighbors for a bit at night we can still see him. It'll work right next door but our other neighbors it won't reach to. Plus, I need another camera for baby #2...
Ive seen the iphone ones but I don't know if I want to pay close to $400!
