Late term delivery - still use due date?


#1

Baby was born at 42 weeks, should I still use due date or birthdate?
The first leap is at 4 1/2 weeks, but if I use due date baby will only be 2 1/2 weeks old when this leap starts…

The blurb about sing due date only mentions premies, it doesn’t mention late term babies, so I’m wondering should I use birth date instead as he hasn’t had that long in the real world to process things to move onto the first leap…
