Alexis Stewart, has welcomed a son, Truman, who was born via surrogate on Tuesday, March 6.
Martha Stewart's daughter is also mom to a little girl, Jude, who celebrated her first birthday Thursday March 8 (so little brother Truman arrived just in time for the party!)
Alexis had struggled with infertility issues for several years before becoming a mom to Jude in 2011 via surrogacy.
"Getting Jude was lucky," she told PEOPLE at the time. "I'm happy, but this has been rough."
