Hi REnee!!My DD is almost 9 months and she has had her bracelet on since she was 4 or 5 weeks old. Since she is little the bracelet is really small. I too wondered what would fit on the bracelet. I ended up putting Adrenal Insufficent because that is all that would fit. I even had to work with the jewler to figure out a way to make the bracelet easy to expand since these little ones grow fast. :) But IT would be a good idea for you to register with Medic alert. Check out their site and they will have all the information about registering and the benefits of being with medic alert.
