     Children pushed in buggies which face away from their parents may suffer longterm emotional and

language problems, according to a study published on Friday.

     The research, believed to be the first of its kind, found that children who were not facing the person

pushing them were less likely to talk, laugh and interact with their parents.

     The findings were based on a study of 2,722 parents and babies and an experiment where 20 babies

were wheeled in buggies for a mile, facing their parents for half the journey and facing away for the other

half. Parents using facetoface buggies were twice as likely to talk to their children while the babies' heart

rates fell and they were twice as likely to fall asleep, an indication that they were feeling relaxed and safe.

     In addition, only one baby out of the 20 studied laughed while sitting in an awayfacing buggy.

     "Our data suggests that for many babies today, life in a buggy is emotionally impoverished and

possibly stressful. Stressed babies grow into anxious adults, " said Dr Suzanne Zeedyk, Developmental

Psychologist at Scotland's Dundee University who carried out the research.

     The study, which was published by National Literacy Trust as part of its "Talk To Your Baby"

campaign, found that 62 percent of all children observed travelled in awayfacing buggies.

     Zeedyk said it would impact negatively on babies' development if they spent a long time in awayfacing

buggies, which would undermine their ability to communicate with their parent at a time when their brain

was developing rapidly.

     Laura Barbour of the Sutton Trust, a social mobility charity which funded the research, said buggy

manufacturers should look closely at the findings.
