The 'Black Swan' beauty and her fiance Ashton Kutcher welcomed their first child, a baby daughter, together in September, just two weeks after the 'Two and a Half Men' star's sister, Tausha, had a son, reported Contactmusic.
"I think (girls are easy)... My sister-in-law had a little boy two weeks prior to us having a little girl and it is completely different, everything," she said.
Kunis revealed she is not too tired as a new mother, and credited breastfeeding with regaining her trim figure.
"Breastfeeding is a great work out," she said.
"I love it. I think it's a luxury to be able to... Be a stay-at-home mum with my kid and I do find that nowadays people can't do that... I was able to take time off and actually raise my child.
