Your baby at 14 months

Everything that lines up at this one age — growth figures from the WHO standard, sleep norms, the milestones whose normal window covers this month, and the vaccine doses due. Percentiles are called centiles in the UK; the numbers are identical.

Growth at 14 months

Median means half of babies are above and half below. Being away from the median is not a problem in itself — following your own curve is what matters.

Milestones in this window

The window is when a skill usually appears — not a deadline. Appearing later than the window is a reason to mention it at a check-up, not to worry alone.

Reference figures, not medical advice. Every baby differs; a check-up answers questions a table cannot.
