Ali Bastian told fans she had undergone a "rollercoaster" of emotions after rushing her two children to hospital.
The Hollyoaks star, 41, who played Becca Dean in the soap, is the proud mum of Isla, three, and Isabella, three moths.
Unfortunately, Isla ended up in hospital over the weekend with asthma after her little sister had been rushed in with a respiratory syncytial virus (RSV) a few weeks ago.
Taking to Instagram sharing a snap of her husband David O'Mahoney holding her eldest daughter, Ali wrote: "Massive thank you to the staff of Kingston Hospital for taking the most amazing care of Isla yesterday.
"Having never had asthma before she had a viral induced asthma attack. (Not a huge surprise though with our family history and her history of allergy).
"It was an utter rollercoaster of a day but finally settled and thankfully able to come home last night.
"Just need to tell my nervous system know that she is safe and home as I still feeling on the ceiling. She was so, so brave but went through a lot. We need a seriously cuddly day today."
Explaining it wasn't the family's first trip to hospital recently, Ali added: "Had the littlest in hospital with RSV a few weeks ago. Little people eh?"
The actress' fans were quick to send their support before Ali updated them with a photo of Isabella sleeping soundly.
She told her followers: "Isla is getting there slowly. Can't believe how many families are dealing with these same viral wheezes.
"Thank you all for sharing your stories with me, makes us feel so much less alone. I honestly didn't know this was a thing.
"She's been very good at taking her inhalers. David and I are just trying to get to grips with the treatment plan and trying to find a bag big enough to carry EpiPens, antihistamine, inhales and a spacer."
Last month Ali said she felt "very lucky and grateful" after giving birth to her second daughter.
The Hollyoaks star gave birth to Isabella Charlotte in February and explained her labour was an "emotional roller coaster", which ended up in her having a C-Section.
The self-confessed "big baby maker" told OK! magazine she went into hospital as planned on 9 February, but the operation was delayed due to emergencies taking priority.
Two days later, Ali, who had gestational diabetes with both pregnancies, went into labour.
She shared: "Isabella was in a really awkward position so it was quite a struggle to get her out.
"She was a little bit black and blue when she came out. She had bruises on one side of her face and a little cut on the other side from the forceps.
"And then I had a haemorrhage. I lost more blood than they were happy with but they treated me for that and got it under control quickly."
