It should be the happiest time of new mom Kendra Wilkinson’s life — and in many ways, it is. The 24-year-old former Girls Next Door star has her own hit reality show, is still smitten with her football star husband, Hank Baskett, and is totally in love with their 2-month-old son Hank Jr. But Kendra has also been going through a secret sadness — dealing with insecurities over her post-baby body — and she shared the story of her emotional experience exclusively with In Touch.
