how long until second baby arrived from induction?

Gina • Teen Mommy to a gastroschisis warrior (10/2/13)💚 And my little baby boy (11/2/16)!😍
I was induced with my first at 34 weeks already at 3cm. It took me 12 hours until baby was born. I'm 39 weeks now and it's been 2 hours so far. I started at 4cm. Not sure where I'm at now. But just curious how long from start to end it took for second time moms? And also how dilated you were  to begin with?
