Washington, April 2 : Halle Berry says her 6-year-old daughter Nahla takes the role of being a big sister to baby brother Maceo-Robert very serious ly.

While talking to Extra, the 47-year-old actress, who welcomed Maceo-Robert with husband Olivier Martinez in October, said that her daughter feels as if one of her dolls has come alive, People Magazine reported.

She loves it because she gets to take care of him, feed him, change his diapers, play and dress him up in different clothes frequently, added the mum-of-two.

Berry added that since there is a five year gap between the kids, there's no jealousy between them. (ANI)
