My dd2 is 19 weeks old. She already has two teeth and there are definately more on the way. She doesn't seem to get any satisfaction from any of the teethers I have offered her and is still really a bit too young/small to hold on to them. As a consequence she is gnawing at her fists and today I have noticed that she is beginning to get sores on her hand at the base of her thumb. What can I do? I don't know what to put on them that will be safe for her to potentially ingest. Any advice gratefully received thank you.
