Recommendations for baby monitor

Hi all! I have a 6 month old puppy that i will be starting to leave for longer periods of time as i start back to work as a teacher. I am in the process of hiring a dog walker and she is crate trained but i thought i would also like to be able to check in with her! I would love any recommendations you all have for baby monitors that are wifi enabled so that i can monitor her throughout the day and then also use for our little human baby who will be making her/his appearance in February! Any recommendations? Thank you!!!
