RE: Baby Monitor for more than 1 child???
We have the Safety 1st Home Connection monitor. It has three transmitters and two receivers. The reception has been great, but I must warn you that the quality is about what you would expect from Safety 1st. The first one we had we returned after about two months because the volume control stopped working. It was within the 90 days, so I just exchanged it at BRU. This one has lasted over a year. My sister also has it and one of her receivers is now doing the same thing after about 18 months of use. However, she is hard on things so I'm sure it has been dropped more than once. :-)
Bottom line - it is a great concept and when it works, works well. Save your receipt and packaging in case you have problems if you get it.
We also have used the FP Lights and Sounds along with an older Graco Ultra Clear that we use simultaneously at my Mom's house. If you want to use your current monitor, I would go buy one of a different brand and see if you can get them to work together. You may have to play with the channel settings to get a combination that works, but it is possible. It would require two recievers, though.
