My 6 month old daughter was using the “ezpz Tiny Cup” to practice drinking water during a feeding under the supervision of both parents. The cup was roughly half full of water, and she brought it up to her mouth herself to drink from it. The cup became suctioned to her face, completely covering her mouth. I had to use a terrifying amount of force to get it free, and she was immediately inconsolably upset once it was removed. There were thankfully no injuries, but I can very easily see how a child might hurt their mouth/nose/face from suction, or aspirate liquid and choke or drown. This event happened so quickly, it took a few seconds before we realized it was stuck.
