***If you’re concerned with the length of these Sippy Cup Leashes posing a choking hazard, keep the length short enough to not wrap around a neck but long enough to still reach the child’s mouth.
My sippy cups work great for these elastic style of sippy cup leashes. If your sippy cups are straight and not contoured, try adding small pieces shelf lining like I did with the last sippy cup leash version, found here. But place little pieces of the shelf liner along the inside of the elastic loop (before sewing it into a loop) about every inch. The tackiness of the shelf liner, along with the tightness of the elastic, should keep the sippy cup leash in place……even on straight sippy cups. This technique just wasn’t necessary for mine.
