I am hoping Luke will be able to fit in this seat until he is 2. By that time Josh (my oldest) will be 7. So hopefully by then, Josh can pedal along on his own bike. It's also possible to maybe have Josh and Ryan (my middle) sit on soft seats and have Luke in a Yepp seat. Also possible to hitch a bike cargo trailer to the back, which would be great if we have another kid, haha! To be determined!
