How much should an 18-month-old baby weigh at most?
⚡ Short answer: There is no single 'maximum weight' for 18-month-old babies — each child's growth is unique, what matters is that the growth curve progresses steadily.

I couldn't figure this out: how much should an 18-month-old baby weigh at most. What do you think?

It's not right to say there's a definite 'maximum weight' for an 18-month-old baby because every child's growth rate is unique. According to World Health Organization (WHO) data, the average weight for an 18-month-old girl is about 10.2 kg and for boys about 10.9 kg. However, the 'maximum' limit you mention corresponds to the 97th percentile on growth curves — about 12.8 kg for girls, about 13.3 kg for boys.
So individual differences are considered normal across a very wide range. Height, genetic makeup, birth weight and other factors also affect this range. If you're concerned about your baby's weight, it's healthiest to look not just at weight alone but at whether the growth curve is progressing steadily. If your pediatrician doesn't see a problem in regular follow-ups, the consistency matters more than the number. I'm curious, how much does your baby weigh?
