Liberty X and Big Reunion star Michelle was devastated when her five-week-old son was admitted to hospital earlier this month after falling unwell.
But, thankfully, the tiny tot has now been given a clean bill of health following treatment.
Michelle, 34, tweeted on Monday night (14 April): "It's been nine days now since our little man was admitted into hospital with viral meningitis (with the chance of bacterial meningitis).
"Even though he was discharged home middle of last week, he still attended hospital everyday for antibiotics and regular blood tests. Today, we received the news we've been waiting for. All recent blood tests are clear and the antibiotics can stop."
Michelle went on to thank fans for their messages of support and paid tribute to the staff at Watford General Hospital, where Aaron was treated.
Although the all clear is happy news for Michelle and husband Hugh Hanley, the singer noted that Aaron will have tests in the future to determine whether his illness had any long-lasting effects.
"He obviously has follow up tests to see if the meningitis has repercussions on his health. But we are hopeful he will be just fine!"
Michelle gave birth to Aaron on 28 February. She and Hugh are also parents to daughter Faith, two.
Earlier this year, Michelle was crowned Disney's Celebrity Mum of the Year, an accolade she told Reveal that she's extremely proud to win.
"Being a good mum is just being there for your children. It's about loving them, taking care of them and providing for them as best you can. Not necessarily financially, but emotionally, and giving them lots of hugs. I love it – it's the best job in the world. Just seeing the delight on their face if you give them a cuddle or give them praise is wonderful."
