I'm a solo parent with a non-walking toddler (I know that's a contradiction, but that's their age group) who weighs about 12kg. Toddler also doesn't grip with their legs when they are on my hip.
They could walk if they wanted to, but aren't ready yet and I think won't for a little while yet.
I'd love a simple carrier I would put on by myself that I could use if I just want to take my dog for a quick walk over the fields etc from my house when the ground is too rough for the pushchair. Supportive so if it was nap time they could sleep while we walked and I could be truly hands free.
Or if like yesterday we were in the car and I needed to drop a couple of small parcels at the post office and I couldn't be bothered to get the pushchair out (turns out that was a mistake!)
