It’s one of the big milestones in the first year of your baby’s life — that exciting day when their first baby teeth begin to break through! Sometime between the ages of four and seven months (on average), your baby’s first teeth should begin to appear. You’ve probably been expecting them for a while since your baby has likely been especially “drooly” and fussy as his/her teeth push through his gums. The first to come through are typically the lower central incisors, familiarly known as a baby’s bottom front teeth. And boy, you didn’t think it was possible, but he/she looks cuter than ever!
