Your Baby’s weight and development

Most babies will not need to be weighed frequently and within Hertfordshire we have several contact points during the first two years either with the Health Visiting team or for self weigh which is facilitated by  the Family Support service.

The chart below shows when the contact points are:

Health Visitor appointments

Your Health Visitor will arrange to see you when your baby is 10-14 days and again at 6-8 weeks. To arrange further appointments when your baby is 12 weeks and 6 months, you will need to call 0300 123 7572 to book onto one of our local Well Baby Clinics.  At this appointment we will review your baby’s weight, find out how things are going and give health advice as needed.


This  is an opportunity to check your child’s weight as well as talk to Early Start staff from the Family Support Service on a variety of health promotions and parenting support topics.

Weighing your baby should happen at a Family Centre using the Self Weigh Stations when your child is 16 weeks, 20 weeks, 8 months and 12 months. These self weigh stations are in partnership with your Health Visiting appointments and will not replace any milestone and developmental checks that you will be offered.

To book your 15 minute appointment for weighing your baby, please click below on the area that you live:

If your baby has crossed over 2 centile lines plotted in the Red Book, please contact your Health Visitor so that they can review your baby’s weight and development.
