Working mothers 'can harm babies' learning'
Many single mothers, like Annette Cowley, must go to work
Mothers who work when their children are very young may damage their future education performance, a comprehensive study says.
Results showed children whose mothers worked when they were under a year old had slightly lower reading scores than the average for the group.
But those whose mothers returned to work when they were older became more confident, with better social skills.
She says the tax credit will give them more choice over whether to go back to work or stay at home with their children in the first year of their life.
The study, commissioned by Ms Harman in conjunction with the Smith Institute, measures children's mathematical and literacy skills as well as aggression and anxiety.
Aggression is judged by disobedience, lying, difficulty concentrating, bullying behaviour, restlessness and destructiveness.
The study found no particular difference in the development of children under one whose mothers went out to work, compared with those who stayed at home, except in reading skills.
There was no significant difference for literacy skills and aggression.
Children aged five to 17 were much less likely to be anxious if their mothers worked, particularly if they worked part-time
The report's author Heather Joshi said it showed there was no real difference if a mother went out to work or not.
Commenting on the slight reduction in reading skills for children whose mothers work before they are one, she said: "We imagine that maternal atttention is important as well as the mother's health and a family free from stress, but we cannot tell that from the evidence we have got."
The institute is now assessing the impact of working on mothers.
The study, which confirmed previous research in the US, also found that poverty and a mother's academic ability influenced her child's educational development much more than whether she worked.
Children of unemployed parents fared significantly worse than others and those brought up in social housing were more aggressive and had fewer reading and maths skills than average.
'Increase mother's choice'
Most working women are allowed up to six months off work after the birth of their child, although not all of this may be paid.
Some have to go back to work out of financial necessity only two or three months after their babies are born.
Harriet Harman used her Wednesday meeting to try to persuade Mr Brown to support her "mother knows best" policy.
She urged him to bring in a baby tax credit of about £70 a week, similar to the childcare tax credit now available for older children.
Ms Harman also asked Mr Brown to bring in legislation extending the period employers must keep jobs open for pregnant employees from six months to a year.
Currently, mothers only get statutory maternity pay for 18 weeks following the birth of their child, but the proposed tax credit would kick in once that ended.
Jill Kirby of the organisation Full-Time Mothers said: "There are financial incentives to go out to work, but no financial incentives to stay at home."
Ms Harman commented: "What we should be doing is increasing the mother's choice when her baby is in early infancy."
