Since having the procedure – during which a silicone band is placed around the stomach to create a pouch the size of a golf ball – Wilson, 43, has lost 30 lbs. and counting.
"It was the right decision for me and I'm doing really well so far," Wilson tells PEOPLE. "It's all about taking good care of myself."
The singer, who is reuniting with Wilson Phillips to promote their new album, Dedicated and their TV Guide Network reality show, Wilson Phillips: Still Holding On, has struggled to lose the post-pregnancy pounds. Wilson has two daughters, Lola, 6, and Luciana, 2, with her musician husband Rob Bonfiglio, 44.
"Having children derailed me a bit," Wilson told PEOPLE in 2010 of her weight struggles. "I'm just frustrated with these pounds."
Wilson Phillips's new album drops April 3 and their series premieres on April 8.
