Length percentiles show a similar trend. Parental height has a strong influence on the eventual height of their children. The weight percentiles of breastfed babies differ from those that are bottle fed. In general, breastfed babies tend to grow rapidly in the first 2 to 3 months, but then grow at a slower rate than the current percentile charts. Health professionals may mistakenly believe that the mothers milk production is inadequate and suggest complementary formula be started.
Babies are individuals.
It is important to look at trends in weight gains over time. Some slowing in the rate of growth is expected after three months of age. Many normal babies will cross percentiles to attain their genetic potential so percentile charts should be used as guides only.
