Some kids lose their first tooth early. She will be 5 very soon, so not to worry. My first daughter was a young 5 when she lost her first tooth.
For all my kids first tooth, the tooth fairy brought a dollar along with a glittery note that stated $1 is for her FIRST tooth. Really, the kids are happy to get whatever from the tooth fairy. My 7 yr old loves it when she finds glitter on her money:)
What a fun little milestone for her....make it magical, that's how childhood should be;)
