Many of the women we've seen so far on this list have spoken of their pride at having children past the age of 40; either because it represented the successful end of a long battle to become pregnant, or because it simply felt like it was the right time in their life to become a mother. That doesn't seem to be the case for Naomi Watts.
The English actor had her first child, Sasha, when she was 39, and then immediately had another son named Kai, born the following year when she was 40. They were conceived naturally and with no issues, and Watts has spoken in the past of wishing that she'd actually had more children and made attempts to start a family earlier. She shouldn't be too hard on herself; she'd had her first child within two years of starting a relationship with actor Liev Schreiber which is hardly a case of dragging her heels!
