In late September, Ms Creasy’s then-newborn was strapped to her as she rose in the chamber to ask Commons Leader Jacob Rees-Mogg to ensure new mothers were supported rather than “rebuked” when returning to Parliament.
Mr Rees-Mogg said in response he thought the rules were “perfectly reasonable and entirely in line with the law”.
Ms Creasy had regularly taken her son and previously her daughter into the Commons chamber.
Neither child had been held by the Speaker, however, unlike in New Zealand in 2019.
Speaker Trevor Mallard attracted global fame as a so-called “baby whisperer” after helping to soothe a colleague’s infant – including rocking, bottle feeding and burping the child – during a debate in the chamber in Wellington.
A year earlier, the country’s prime minister Jacinda Ardern became the first world leader to take their baby on to the floor of the UN General Assembly.
