hi! Currently living in Estonia and im surprising my husband with a trip to Stockholm the 2nd week of Oct and we're taking our 9month old. We'll be walking mostly but I wanted some insight! Should I bring my Quinny zapp extra stroller or our heavy duty Emmalijunga stroller? We're coming by ship so I dont think bringing a stroller will be an issue...I'm just curious if I will need something with better/sturdy wheels on the streets of stockholm....thanks!
