Heather Morris is keeping busy! The Glee actress opened up to Us Weekly about her upcoming nuptials to fiance Taylor Hubbell and her son Elijah's latest milestones while attending the Gymboree and Eric Carle Collection Launch Event with her big boy in Santa Monica, Calif., on Friday, Sept. 5.

Morris, 27, and Hubbell welcomed "Eli" (as she so lovingly calls him!) in September 2013 and got engaged last month. The star admits becoming a mother was a "life-altering change," but planning the pair's wedding has also been a special time in their lives.

"It's just more exciting between us. Just like the future plan was, we always wanted to get married," the 27-year-old told Us. "We've been looking forward to having a huge, fun reception."

Elijah — who turns 1 on Sept. 28 — has entertained the high school sweethearts in the meantime. "We love playing with balls, so that's really, really great. We love going outside," she said of her boy. "I think it's just like a life-altering change. You don't really know, and then once you're in it, you're like, this is fantastic," she added of motherhood. "Every stage is great."

Morris has kept details of her son private for the most part, but admitted that she tried to keep calm as much as possible during the pregnancy. "When you stress out, it's a lot harder," she explained.

As for getting back in shape, the dancer (who has gone on tour with Beyonce in her day) didn't seem to have any trouble. "We go on a walk every morning," Morris told Us. She also has been burning calories at dance classes.
