Babies born into large families less likely to thrive, say scientists
An investigation into why some babies grow slower than others found a fourth child is twice as likely to develop slower than a first child. Even second and third babies are more likely to "fail to thrive", according to the study.
Academics at Bristol University also discovered a strong link between the height of parents and their baby's growth rate. Babies of short parents were eight times more likely to grow slowly when compared with babies with tall parents.
