Do they make bitter apple for kids?

My child still sucks her fingers while self soothing at bedtime. Always while holding her Lovey Waddy.
Anyway the dentist said she could develop buck teeth so he recommended this bitter apple stuff.

I can only find the formulation intended for dogs.

Any help out there?

Meet 'Waddy'

Jamie has had this green Carters Lovey since we brought her home. Though we referred to it as her 'Lovey' all along, she informed us at about 10 mos old that Waddy was his name, and her other Lovey who is a yellow Care bear is Yaddy. Yaddy is most definitely her substitute lovey though, as we found out when Waddy was missing for
a day or so - there were sure alot of tears. The Waddy rule I have instituted is to keep that from happening again, Waddy isn't allowed downstairs or outside of the house. Aren't I tough?
