Looking for recommendations

I loved baby wearing with my first but we stopped when she outgrew the wrap. I’m due my second in may and my first will be 2 so I’m looking for recommendations we will be using the wrap until he gets too big for it but I’m kinda worried about what comes after that 😅 things like walking the dog with 2 babies isn’t going to be easy. My first can walk but needs reins so i definitely think I will be baby wearing this one for longer 😂 my problem with other carriers is they just look so big and bulky :/ I’ve always been tiny and also have back problems including osteoporosis
