My daughter had her first two bottom one's at 4-4½months old! She had her top two at 6mo! She has 20 teeth total now! My son is teething issues for a month but no teeth yet! L😉L I have heard little girl's move up fast then boy's! 😂
Teeth come in at different times by 8 month my baby had 10 teeth and now at 16 months he almost has all 20. My nephew born 3 months before my son only has 6 now.
