It is a button so when you have the baby you can push it.. it sets the details.. I was so happy when I got to press it the first time I had my baby..
You get to set date when baby was born, get a congratualions and option to set baby's details. That's about it. Forum and everything else still the same.
Kind of wondering the same...I think u push it when ur baby arrives and maybe it gives an option to tell ur story...or means we are done with the app?? Mine just showed up a couple days ago...I am 37 wks today
