2 Camera Monitor

Looking for recommendations for a new monitor, preferably with 2 cameras as I am 6 weeks pregnant. I have a Motorola for my 2 yo that was supposed to be expandable but I can’t find just the camera anywhere, and it will randomly loose the signal out of no where, especially in the middle of the night. The loss of signal had been getting worse recently, the other night the signal kept going in and out repeatedly for a few minutes and makes a loud beeping noise when it goes out.
