The 39-year-old, who is running to succeed President Emmanuel Macron in next year's election, announced at the end of March that she was three months pregnant with a "miracle baby".The unplanned pregnancy followed a miscarriage and several unsuccessful attempts at assisted reproduction and in vitro fertilisation (IVF), which had put her plans for another child on hold.The left-wing candidate said the news left her feeling "dizzy", but that the decision to continue campaigning was "never in doubt".Instead, she had to consider how to navigate the race as the first French politician to run for president while expecting.She is doing so at a crucial stage in the campaign, with candidates on the left, centre and right jostling for position just months before an election that may come down to a face-off with the far right.-'Exhausting'-Tondelier said campaigning while pregnant "is a real challenge", recalling having to vomit in train toilets while travelling to support fellow Greens in local elections.But she has shown little sign of slowing down, travelling across France in an electric van in July while seven months pregnant and as the country grappled with a heatwave.
