Moving closer to family pros and cons

how many of you moved closer to family after having kids? Is it beneficial? Currently, we live about 30 minutes from them. They are wanting us to move closer though so they can help more. My only thing is I don’t want it to turn in to people showing up unannounced and company all the time. What are your thoughts? Bc we are going to need their help but I just don’t want to be right up under them. Give me all the pros and cons. I’m on the fence.
