Two under two.

Melissa • Married to the love of my life! Had my sweet Madison on 07/31/15 and now due with baby #2 Oct' 16.
I'm pregnant with baby number two and was wondering what diaper bag would be best for everything I need for a newborn and a 14 month old? Any advice mommys? Preferably a backpack style, since I don't care for the shoulder straps. Please help!!
