You could always extend the cords or ropes of the pull-toys, especially if you have or can find material that is similar. However, you must keep in mind that the main reason for the short ropes is safety. If the pull cords were any longer, then they would pose a problem of tripping or tangling the child’s legs and feet as they try to walk with the toy. There could also be an issue of choking if the cord becomes wrapped around the child’s neck if left unattended to play with the pull toy. If you do decide to extend the cords, make sure they do not cause these problems for the toddler.
