Head circumference for an 18-month-old? My mother-in-law says one thing, I read another.

For an 18-month-old, average head circumference is about 47–49 cm for boys and 46–48 cm for girls. Of course, this varies based on WHO (World Health Organization) growth curves — what really matters isn't a single measurement but your baby's own growth curve progressing steadily over months.
If there's a small difference between what your mother-in-law said and what you've read (like 2–3 cm), both sources might be in the normal range — there's also room for measurement error at home. But if there's a big gap or if you're worried, your pediatrician's measurement during an exam is the most reliable reference.
Wishing your little one a healthy journey forward. 💛
