During her initial return in February, Rachel brought her baby daughter and husband to the studio to meet the Countdown cast and crew.
She posted a picture of the trio on set online and spoke of her relief at still being able to do complicated maths equations.
The Channel 4 star told her followers: “First block back at work done and dusted and I can still sum post baby… phew!”
Just last month, Rachel and Pasha celebrated one year of marriage and marked the special occasion with a sweet family photo.
“What a first year,” wrote the newlywed on Instagram alongside the social media snap.
Rachel, who tied the knot in Las Vegas on June 28 2019, wrote: “One year later! Celebrating today with our extra smiler in the family.
“Love these two. What a first year it’s been! #firstweddinganniversary #twinning.”
