It comes as the results of a new survey show growing trends around how mothers-to-be are sharing their pregnancies online.
They reveal nearly 90% of mothers have seen an image from a friend’s scan and nearly a third (32%) have seen a shared professional pregnancy photo-shoot.
More than a quarter (28%) have seen a picture of a body-painted bump and a fifth (22%) have viewed a photo of a positive pregnancy test.
Behind the joint survey are the parenting site Netmums and the DH’s Start4Life campaign.
The results also show 44% think it is nice for their pregnant friends to share information, and many see Facebook as a place to share advice and seek help.
However, 44% of respondents said they felt that people are beginning to over-share.
In response, Start4Life is urging mothers-to-be to share information about their health and the steps they’re taking to give their babies the best possible start in life, both online and offline.
Start4Life, the sister brand to Change4Life, has launched a free booklet for all pregnant women to help them keep healthy throughout pregnancy and beyond, by moving more, eating healthily, giving up smoking and avoiding alcohol.
Health minister Dr Dan Poulter said: ‘Staying healthy in pregnancy is vital to give babies the best possible start in life.
‘We want to do everything we can to reach out to pregnant women and help them live the healthiest lifestyles they can.
‘These new materials from Start4Life simplify the information out there and provide clear advice on the importance of a healthy pregnancy.
‘The sheer volume of information available to pregnant women – on Facebook and elsewhere – can make it hard to find the best advice. Start4Life will help them to take simple steps to stay healthy for themselves and their baby.’
Dr Dawn Harper, Start4Life ambassador, GP and television presenter, added: ‘Many think of Facebook as a place to share pictures of bumps and tales of cravings, so it’s encouraging to see that many mothers think it would be better used to discuss matters such as health, and are keen to offer support to other mothers.
‘However, to do the best job at this, it’s important we’re well informed, and Start4Life is a brilliant one stop shop that can answer all the questions on pregnancy you, or your Facebook friends, may have.’
The new Start4Life booklets are available to all pregnant women through their midwife or GP.
They contain space for mothers-to-be to enter personal details including their midwife’s name and number, their baby’s first scan and questions for future appointments.
In addition, there are also healthy recipes and tips, myth busters and exercise suggestions.
The information is also available online on the Start4Life website.
