Stacey Solomon has revealed her baby son Rex has reached a massive milestone.

The Loose Women presenter and her boyfriend, Joe Swash, welcomed their first child together on May 23. And taking to Instagram over the weekend, the 30-year-old revealed that Rex has already reached a pretty big milestone: completing stage one of his swimming lessons. Stacey shared a number of photos of her "under water pickle" from after his swimming lessons. "Last week Rex completed stage one of his swimming lessons so today we got to celebrate and take some underwater pictures," she began the caption. "They’re incredible I’ve never seen anything like them. Rex we are so so proud of you," she continued. "Your brothers LOVED seeing you splash and swim today and they can’t wait till you’re in the pool playing bulldog and water polo with them." "We love you to the moon and back Rexy bum! WELL DONE," she added. Joe and Stacey announced they were expecting their first child together back in February this year. Joe appeared on Good Morning Britain soon after sharing the news on social media, where he told how they were "really happy, really excited" to be parents. He added:

"We're really happy, really excited. We just feel blessed... I'm well trained I'll be fine, we'll be fine it'll be good. She's all good she's excited we just can't wait for it to happen now."

Stacey has two sons from a previous relationship: 10-year-old Zachary and 6-year-old Leighton. Joe has one son, 11-year-old Harry.
