A baby boom has pushed British maternity services to a "crucial tipping point", according to the Royal College of Midwives (RCM).
The trade union said that in some areas the number of births has risen by 50%, leading to a massive shortage of midwives. It said that the midwives who are working are under intense strain and hospitals are struggling to cope.
In a report to be published in parliament on Tuesday, the RCM warned an extra 5,000 midwives are needed in England alone to deal with the highest birth rate in 40 years.
It is calling on the Government to provide a guarantee not to cut midwife training places.
Half of the 260 women surveyed in the The Royal College of Midwives (RCM) and Netmums study revealed that antenatal depression affected their relationship with their baby.
