Hi Deni
I actually have the Kinderkot, which I loved when my DD couldn't stand up and walk However, the last time we took it to a friends house and I put her in it to go to sleep she was walking around and turning it over and upside down like she was stuck in a big beach ball and was rolling around in it, so if you little one is standing up and walking and doesn't quite get the concept of lying down and going to sleep, I would go with the Phil and Teds. I wished I had purchased one of those instead now, as we can't use the Kinderkot at the moment.
Hope this helps.
Nik
