I got the regular size Gemini as my diaper bag. It is gorgeous but too big for 1 baby so I’m saving it for when I have more kids :) I got the mini sage during the spring launch and it’s so beautiful!!!!! It’s the perfect size for just 1 baby. I know these aren’t diaper bags but I just love them. I haven’t tried to carry backpack style so can’t comment on that, otherwise obsessed. My Gemini is Forrest. Looking to get the coffee also. Love them that much!
