Does anyone out there have a tip on how to control 20 month old walking twins in the park and also manage the twin buggy? When I let them out for a run around one goes in one direction and the other etc etc Now they are getting better and faster at walking and will soon be running. I have short reins but it is very difficult to wheel the buggy and hold onto the reins. I bet there is a supermum out there who has the solution. Please advise!!! Thanks!
