UK lawmaker reprimanded for bringing her baby to work

London (CNN) A British lawmaker has asked for an investigation into the rules around bringing babies into the House of Commons , after a member of Parliament was told she could no longer bring her child into the chamber.
"Mothers in the mother of all parliaments are not to be seen or heard it seems..." Creasy wrote on Twitter following the incident.
"My son is 13 weeks old, so I can't really leave him on his own and I don't have any maternity cover.
So I kind of can't win here," Creasy told the BBC's Victoria Derbyshire on Wednesday.
"We are currently in communication with Stella Creasy about this matter," they added.
Creasy told the BBC that while she wouldn't bring her other child, a toddler, into work "because she would find everything breakable or spreadable in the parliamentary chamber within five minutes and cause havoc," her infant son was "completely silent."
Referencing the new rules published in September, Creasy, who said she had brought her first child to the House, said: "I don't understand what has changed.
What I do understand is that there are barriers to getting mums involved in politics and I think that damages our political debates."
Creasy lost a battle with the Independent Parliamentary Standards Authority this summer after she was told she could not hire a locum to cover her maternity leave after the birth of her second child.
Responding to a suggestion Monday by journalist Julia Hartley-Brewer that she should "go and enjoy her maternity leave with her baby," Creasy tweeted: "Without maternity cover I don't actually get maternity leave as no one else to do my job."
In 2019, New Zealand Labour MP Tāmati Coffey brought his six-week-old son to the debating chamber , where the child was later held by the house speaker.
And Prime Minister Jacinda Ardern , who became New Zealand's first premier to take maternity leave and the world's second elected leader to give birth in office, made history by bringing her three-month-old daughter into the United Nations assembly hall in 2018.
