Best diaper bag for 3 little kids

J

I have a 3.5yo, 1.5yo and due in February.

This is the current diaper bag I have and it’s getting tight!

I still have to carry around an extra set of clothes and pull-up and undies for my 3.5yo just in case, and 1.5yo still in diapers. Then add a newborn who will go through more clothes and diapers than the other two. I need a bit of a bigger diaper bag without being toooo big.

Any recommendations? TIA!🤍
