Katherine HeiglKatherine Heigl is still in awe with her 20-month-old daughter, whom she adopted with husband Josh Kelly. But the 'Life As We Know It' actress admits connecting with Nancy Leigh Mi-Eun (Naleigh) had its challenges because she wasn't ready to put her career on hold.

"I had a lot of complicated emotions about it because I chose to go back to work," she says in the October issue of InStyle. "I love what I do and -- this isn't just making excuses -- if I weren't fulfilling this thing in me to perform, to live out my passion, I don't know that I would be the mom I need to be."

Heigl now only works three months a year, instead of nine, adding the mother-daughter relationship has improved.
