LA – The 43-year-old Christina Aguilera is very protective of her children. In a new interview singer, who shares son Max, 16, with ex-husband Jordan Bratman, and daughter Summer, 10, with fiancé Matt Rutler, said watching her children grow reminds her on her own childhood traumas. She said: “Your kids trigger things in you that you don’t want them to go through. And it’s almost like you’re reliving this whole thing again. I love my son and my daughter so much, and you do want to shield and protect them from the world. But they have to learn their own lessons. I’ve seen so much so young. You just want the best for your kids.”
