Tiffani Thiessen has more important things to worry about than fitting into her pre-pregnancy jeans. “I haven’t dropped all the baby weight, but I’m getting there,” the Dinner at Tiffani’s host told Us Weekly on Saturday, March 12, at the grand opening of Bowlero Bowling Alley in Woodland Hills, California. “I try not to stress myself. As long as I eat healthy.”

The Saved by the Bell alum, 42, and her actor husband, Brady Smith, are the parents of daughter Harper, 5, and son Holt, 8 months. 

“Here’s the thing, I am still nursing,” Thiessen told Us. “My No. 1 goal is to make sure that Holt is getting what needs. … Once I stop nursing that is usually when I drop most of the weight.”

The actress also opened up about the age gap between her two kids. While stars such as Emily Maynard and Hilaria Baldwin are both expecting again less than a year after welcoming babies, Thiessen sees the benefit in waiting. “Harper is the best big sister!” she raved. “The bigger age gap is great. She is super helpful … now that he is a little more ‘durable,’ as I say. He is easier to be with and play with. He is sitting up and crawling and doing all those kinds of things.”
