Good day girls. Could you advise me? I'd like to walk with my little one outside for longer now. It's almost a month old. I think I should buy her an outdoor jumpsuit or something else. So that it doesn't look like we walked for two weeks and everything grew out then. And it's summer. But so that it's warm now and then so that it doesn't just lie there. I don't even know what to buy her for walks so she can go out. What would you recommend
