Gracie had to have 6 of her baby teeth extracted... but I did hear that they loose their teeth from 5 months-a year... I could be wrong... but I thought I heard it somewhere... someone will correct me if Im wrong Im sure...
I always found Gracie chewing on her baby teeth... and playing with it... lol funny to watch them... good luck I hope you start finding them soon
oh and you may just have to check your baby's mouth every now and then because Gracies friend Toby I think was a little older then Gracie was when he lost his baby teeth... and his mommy didnt realize it until I looked in his mouth
