Why is it important to weigh babies?

Since being introduced in the early twentieth century – weight checks of babies and infants has been a fundamental part of monitoring growth.

After birth, babies lose weight, but by the time they are a fortnight old, most babies will have regained their birth weight.

Weighing the baby is important because should the baby fail to meet these norms, it can reflect problems with the baby’s health – and so is a fundamental part of diagnosis.

What can be spotted by baby weighing?

When the baby is weighed at birth – and a low birth weight is diagnosed he/she may be at risk of complications.

Low birth weight can be associated with a premature birth, and it can be difficult to separate between the two if this is the case. In general however: the lower the baby’s birth weight, the greater the risk they will face.

According to the World Health Organisation, babies with a low birth weight have a higher risk of dying in the first 28 days of life.

Common problems of low birth weight babies are:

  1. Low oxygen levels at birth

  2. Inability to maintain body temperature

  3. Difficulty feeding and gaining weight

  4. Infection

  5. Breathing problems

Nearly all low birth weight babies require specialised care in the Neonatal Intensive Care Unit (NICU) – and there’s a 95% chance of survival for babies weighing between 1.6kg and 2.6kg. Find out more at Childrenshospital.org.

How often babies should be weighed

The UK’s paediatricians Coventry Consensus recommendation (1998) states all babies should be weighed at birth, and those who are growing normally should be weighed ‘at immunisation and surveillance contracts’ – giving five weights in their first year.

The NHS adds, that a baby should be weighed a maximum of once a month until they are six months old, once every two months from 6-12 months and after aged one every three months (maximums).

However, if there are concerns over your baby’s health - or you ask for a more frequent assessment – then they can be weighed more often.
