JennyHi Sara,
It is tough when they are small to get them to wear their Medical ID Jewelry. Lisa had a good idea to wear the bracelet around there ankle. Not so sure of a necklace at that age. On my website I have the jr. stainless steel bracelet that you can wear around the ankle and it does take 2 people to get it off.
Also the soft red Medical Alert ID wristband that has velcro with the hidden pocket to put your info on a waterproof card is great. Cody always wore that. It was soft & he liked red! The shoetags are great you can put them on anything. Just some suggestions.
