Mouthing and Biting

My son has sensory processing disorder where his mouth is under sensatized and it feels like it has novocaine in it constantly. As a result, he sensation seeks with his mouth by constantly putting non-food items in his mouth and chewing. To help him with this, we use an electric toothbrush to give him that input that his mouth is seeking. When he was younger, we also used vibrating teething rings as well. I'm not sure if this is an issue for your daughter -- I can't seem to remember when babies/toddlers stop mouthing objects -- but you may want to run this past your doctor and see what he/she has to say.

my 3 yo still does this. I guess it will eventually go away.

My daughter will be 3 the end of February, and she just finally got out of that stage about 6 months ago!! It's really annoying, I know! But I've come to realize that some kids just have more of an oral fixation than others. There really wasn't anything I could do to eliminate it, I just had to keep taking the things away and telling her "no mouth". She eventually got over it!
Good luck!

My 4.5 yo is *still* in this phase =) Good luck w/ breaking it and if you figure it out, please let me know!
