Mayim BialikFormer child stars are famous for their all-too-frequent troubles -- the untimely death of Corey Haim is perhaps the most dramatic example in recent memory, but brushes with drugs and the law have plagued young stars from 'Diff'rent Strokes' to 'Full House.' Just this week, former 'Family Ties' baby Brian Bonsall was sentenced for charges of assault and felony menacing.

It's refreshing to see a one-time child actor emerge from the experience unscathed; 'Blossom' star Mayim Bialik is one such success story. The actress has been working steadily in television after a lengthy hiatus -- during which she earned a PhD in neuroscience and started a family. Bialik talks to PopEater exclusively about keeping it together in Hollywood, balancing motherhood with her career and her upcoming arc on 'The Big Bang Theory.'
