Auto-Populate Monthly tabs from based upon data entered on aggregate data sheet

[Ndavids1]

Hello All,
I'm hoping this is the correct forum for my query. I am working on a project where I need to be able to enter my data in one location on the "ALL DATA" sheet; then have the data entered in the sheet populate into the corresponding monthly sheets.

For example, patients born in January ("MONTH" column D) will have their row data copied to the sheet called, "January 2019", and so on, for each patient by month. I've attached an example spreadsheet below.

Does anyone have experience with this type of macro, or formula? (I'm a novice, so please take pity on my soul!)
