Backpack diaper bag


I'm going to have my 2nd child early June. I used a messenger bag style bag for my son when he was little but ended up with a generic backpack and I loved it more.

My MIL said she would get me a backpack diaper bag to use for BOTH kids (son will be about 2.5 when new baby gets here and is starting potty training so he will have extra clothes)

Any recommendations on a good backpack diaper bag that will hold stuff for TWO kiddos?

Thank you in advance!
