Good to know
You really are not the only one
Numbers help more than reassurance. Drag the cards — every one of them is a study, not an opinion.
46% — of children in daycare get bitten
In a year-long study of 224 children, 104 of them were bitten at least once — 347 incidents in total. If it happened in your group, it is not a bad group. It is an ordinary one. (Source: One-year daycare study, 224 children)
3× — more hitting and biting than later
Two- and three-year-olds kick, bite and hit roughly three times more often than the same children will at any later point in childhood. The peak you are living through is the peak. (Source: Scientific American, developmental research)
94% — of babies show physical aggression
Of 477 mothers of children aged 6 to 24 months, 94% reported at least one of nine physically aggressive behaviours in the past month. Nearly every child. Including the calm ones. (Source: Journal of Pediatrics, 2019)
30 months — is where biting peaks — then it falls
Biting rises from around 13 months, peaks between 16 and 30 months, and drops sharply once a child turns three. You are not at the start of a long road. You are near the top of a hill. (Source: Daycare incident research)
14% — of children bite repeatedly
Only about one in seven children bites as often as weekly. The much larger group bites once or twice and never again — which is very likely your child. (Source: ParentData / Emily Oster)
3.13 bites — per 100 days at daycare
Boys 3.66, girls 2.30. The gap between them is far smaller than the reputation suggests — biting is not a "boy thing", it is a toddler thing. (Source: Childcare incident study)
0 — long-term developmental meaning
This is the sentence worth keeping: the research literature treats biting at this age as a normal developmental phase with virtually no lasting developmental significance. It does not predict who your child becomes. (Source: Developmental literature review)
50 words — is the two-year mark worth knowing
Biting fades as language arrives — the fewer words, the more the body has to say it. If your two-year-old has fewer than 50 words and no two-word phrases, mention it at your next check-up. Not as alarm. As information. (Source: Paediatric developmental guidance)
Questions parents ask at 10pm
How common is biting in daycare, really?
In a year-long study of 224 children, 104 of them were bitten at least once, which is 46 percent, across 347 separate incidents. If it happened in your group, that is not a bad group. It is an ordinary one.
Do boys bite more than girls?
Slightly, and far less than the reputation suggests. One childcare study measured 3.66 bites per 100 days for boys and 2.30 for girls. Biting is not a boy thing, it is a toddler thing.
At what age does biting peak and when does it drop off?
It rises from around 13 months, peaks between 16 and 30 months, and falls sharply once a child turns three. If you are in the middle of it, you are not at the start of a long road. You are near the top of a hill.
How many children bite over and over rather than once or twice?
About 14 percent, roughly one in seven, bite as often as weekly. The much larger group bites once or twice and never again, which is very likely your child.
Does biting now predict anything about my child later?
No. The research literature treats biting at this age as a normal developmental phase with virtually no lasting developmental significance. It does not predict who your child becomes.
