Recommend baby camera

Ti

I’m needing recommendation for the best baby monitors camera systems.

I have a 2 1/2 year old son and I know for a fact that when baby sister is born and takes naps he’s not gonna nap at the same time. So I’m thinking of getting a camera to watch baby while I’m up with son , cleaning , etc.

Prefer something with audio so I can hear baby. May use with son also.

What’s something you like about yours and things you don’t like?
