The 48-year-old 'Alice in Wonderland' star, who has two children with partner Tim Burton, said she finds it difficult juggling her career with taking care of her children, reported Contactmusic.
"Juggling motherhood with acting is hard and I am always dropping balls all the time. You always feel you are doing everything badly," she said, adding Burton is a great father.
Carter says she is in high position with her career, but busy schedules leave her exhausted.
She said she had a perfect childhood and hopes to be as good a parent as her own.
