I've got a jogger with a toddler seat too.
We don't often put the toddler seat up but sometimes when Yasin is tired he'll ask for it so I'm glad we have it. There's nothing worse than being stuck with a tired toddler who doesn't want to walk anymore when the car is miles away.
I'm thinking of getting a side by side now because Imran gets the grumps these days if Yasin's seat is up and he can't see.
