My brother bought DD a 12ft trampoline for her 2nd birthday...very extravagant I know but DD absolutely loves jumping more than anything in the world and she is the only LO in the family. Long story short but the zip never fully closed and only ever went down half way. I didn't like to complain as it was such an expensive present, it took a long time for DB and DH to assemble as they put it up in the pitch dark the night before her birthday (winter baby), DD is physically very capable and as she was only 2yo I was always with her when she was on it so could spot her. Fast forward 1.5 years and I'm starting to think what to do when DS (9m) is old enough to want to go on. How can I make it safe for him? Is there additional part I can buy without having to replace the entire net?
