Girls, my daughter is turning three on June 3rd. I want a lightweight stroller. We love going for walks on uneven terrain, you know. For now we're managing with a jogging block. I know that some kids start walking in strollers and don't sit properly in them. I'm thinking of buying a really light stroller, and taking the jogging block out into the woods, or selling the old stroller and buying a normal, decent one with larger wheels for a walk? Is it even possible to combine maneuverability and lightness at all?
