Nutrition and weight - Start for life

Your baby's weight and height

Steady weight gain is one of the signs that your baby is healthy and feeding well. It is normal for babies to lose some weight in the first few days after birth.

Your baby will be weighed during their first two weeks to make sure they are regaining their birthweight. Most babies are at, or above, their birthweight by three weeks. Your baby's length may also be measured at some of their developmental reviews.

A midwife or health visitor will support you if your baby loses a large amount of weight or does not regain their birthweight by three weeks. They will talk to you about how feeding is going, possibly ask to observe a feed if you are breastfeeding, and look at your baby's health in general.

How often should my baby be weighed?

After the first two weeks, your baby should be weighed:

  • no more than once a month up to six months of age
  • no more than once every two months from six to 12 months of age
  • no more than once every three months over the age of one year

Your baby will usually only be weighed more often than this if you ask for it, or if there are concerns about their health or growth.
