"Jack and I are super excited to share with you all that we are expecting our second baby!" Lisa wrote on her blog raddestmom.com. "I am in my second trimester, feeling great & trying not to eat everything in sight."
The happy couple are also parents to a daughter, Pearl, who was born in April 2012.
"We feel so blessed that our family is growing & Pearl will have a little brother or sister to play with," gushes Lisa. "It’s crazy to think that we will soon be a family of four!"
Lisa will have some great new material for her blog now that she can openly write about her pregnancy. She hasn't been shy about child-rearing thoughts, like what to do when rampaging toddlers are ready to throw down.
"What’s wrong with letting BABIES duke it out a little?" asks Lisa. "I’ve learned from experience with my nephews and friends with small kids that it usually works out better to let them take things from each other and learn how to defend themselves in return. After all, babies really are just cute little cave men."
