Creating a Dynamic Children from Input fields with indexing to day number

I am trying to create an Itinerary in admin view, for admin to add itinerary customised to day by day; in the sense that Day 1 - Title -Description; Day 2 - Title - Description; and so on..... now there is a AddDay button which On Tap should Add the fields for adding day 3, and when taped again add day 4 and so on. With reference to the screenshot below the addDay button should add a Day 3 with proper indexing of days and title, description fields. And the red crosses for removing a day as well.
