The 44-year-old took to Twitter to thank the doctors who cared for three-year-old Marnie Mae, but didn’t clarify what was wrong with her.

She wrote: “After 4 days of a poorly 3 year old I can only thank every doctor and nurse who looked after my MArnie. #SaveTheNHS [sic].”

Earlier this month Tamzin shared a cute snap of Marnie with her older sister Florence Elsie, as she prepared for her first day at nursery.

The former EastEnders star wrote: “First day of big nursery calls for same hair as big sister [sic].”

Tamzin, who shares the girls with ex-husband Tom Ellis, recently revealed she plans to take a break from working to spend more time with them.

She told the Mirror: “I’ll have as much time off as it takes to hang out with the girls because it feels like they need me at the moment.

“What with filming and my theatre commitments, I was literally working from 6am until 7pm or 8pm – and barely seeing my kids.”

The last episode of Tamzin’s latest project New Tricks aired last night, and she revealed her sadness over the end of the show.

She wrote: “Ok.It’s time to say goodbye to New Tricks.12 series.I have only appeared in 21 episodes but to all who worked on it… Thank you & congrats [sic].”
