We got the cheapest vtech one from Argos and it’s still going strong after nearly 4 years, never had any problems with it.
I have this one and absolutely love it. https://amzn.to/3RPwFss you get 15% off if you set up a baby wish list on amazon too
Recently bought this: https://amzn.eu/d/aBwlHuh I am really happy with it ☺️
@Paige is that just the audio one or one with a monitor?
@Kerry with the camera as well
https://amzn.eu/d/0OXhIY5 not sure if this is a bit pricey but I’ve found it absolutely brilliant! You can move it from your control if they move out of camera sight and you can press a button so that they hear your voice which soothes them when i’m on my way to them!
