I now see 2 teeth protruding on my 5-m.o. baby's upper gum. Is it too early or just on time?

A majority of babies sprout their first tooth when they are between 4 and 7 months old. An early developer may get glimpses of his or her first tooth as early as 3 months, while a late bloomer may have to wait until he's a year old. There are even rare cases when a baby's first tooth is already visible at birth! So at 5 months, your baby's on the right track :)

Both of my kids had their first tooth cut off (lower gum) at 4 months old. Thus, it is normal for your baby to have her first tooth at 5 months old, although the norm for the first tooth to erupt is around 8-12months.

Your baby's right on track! My girl had her first set at 10 months :)) So tiring to wake up everyday with the hope of seeing two pearls!!

My baby had his two upper teeth when he was 3 months old.
