Diaper bag

Al

I’m due with #2 in December. I will have a newborn and 11 month old 😅 I tend to over pack, so I’m going to need a decent size diaper bag, preferably a backpack style. Any suggestions? I have the Joie Bean Large Diaper Tote bag and it’s just big enough for everything I need for my 4 month old right now. I can imagine having to pack two babies with this bag
