What size pockets are you getting inside your WW backpack?

[lizard]

I'm so excited to order a WW backpack!!! Thinking of getting 5 or 6 interior pockets, but I'm not sure what size(s) to get. (I'm due with Baby #1 in May, so I have no clue what size pockets I'll need.)

If anyone has any advice/pocket meassurements (width & depth), that would be great!!

Thanks,
Liz
