The government has pledged to stop children growing up in B&Bs and to make childcare more accessible for families on Universal Credit as part of its child poverty strategy.
It expects to lift around 550,000 children out of poverty by 2030, "the biggest reduction in a single Parliament since records began", with measures including scrapping the two-child benefit cap.
Homelessness Minister Alison McGovern said the effect of temporary accommodation was a reason attributed to the death of some children and babies, and that she would consider herself "a failure" if newborns were still living in B&Bs by the time she finished her job.
Homelessness charities welcomed the plans, but called for greater changes to lift people out of poverty.
