Your child's physical growth during the second year, although considerable, is less rapid than during the first year. In the second year, toddlers gain an average of1.5 kg (3 lb) to2.5 kg (5 lb) and grow an average of 7.5 cm (3 in.) to12.5 cm (5 in.). Healthy growth is different for every child, and your child will grow at his or her own pace. Your child's natural growth rate may be slower or faster.
As toddlers start to walk and become more active, they develop leaner and more muscular arms and legs and lose fat around the face and tummy. They also lose some of their baby look.
In the second year, the molars usually begin to come in. These large and flat teeth may cause your toddler pain before and while they are erupting through the gum tissue. This may cause irritability, disrupt sleep patterns, and change your toddler's behaviour. For more information about tooth eruption, see the topic Teething.
