Any new mother will know what Tia Mowry was going through when the star admitted she broke down in tears when she returned to work.

The actress returned to work just weeks after the birth of her son last year (11) because she felt "guilty" for leaving him behind.

The former Sister, Sister star gave birth to son Cree last June (11) and was back filming U.S. TV series The Game in September (11) - but she was distraught to be parted from her baby boy as she shot the show.

When you go to work, you're spending time and hours away from your child, and I would find myself crying and feeling guilty that I wasnot there

She tells People.com, "There's a lot of things going on in your mind asa new mom. When you go to work, you're spending time and hours away fromyour child, and I would find myself crying and feeling guilty that I was not there. "I had to change my perspective on the whole thing and say, 'I am doing this for my son.

I am working to give him a better life, to provide him and my family with the best.'" Mowry now takes young Cree on set with her - and she admits the cast and crew are enamoured with the tot.

She adds, "I feel blessed to be able to bring my son to work and to share with him what mommy does at such a young age. Now, it's like second nature to him. He's in the hair and makeup trailer and seeing mommy get ready... he always puts a smile on my face, keeps me at ease. And he was the hit of the whole set. Everybody loves Cree so much".

Meanwhile the new mum is sharing her pregnancy secrets with other expectant women in her new motherhood manual.

The former Sister, Sister star struggled with nausea in her first trimester before giving birth to son Cree, her first child with husband Cory Hardrict, last June (11).

Mowry kept a diary throughout her pregnancy, and she opens up about herown experiences in new book Oh, Baby Pregnancy Tales and Advice from One Hot Mama to Another - and the actress hopes the tome will help other mums-to-be, like her twin sister Tamera.

She tells People.com, "I don't mind sharing with the world the most amazing gift that God has ever given to me. I think it's good to basically share with my fans what it's like to be a mom, the joys and the challenges.

"I think with a lot of pregnancy books, it all came from a medical standpoint, and you were missing the fun, kind of girlfriend approach.

You don't want to be constantly reminded of all the bad things that can possibly go on through your pregnancy. You want to feel empowered".

The book hits shelves later this month (May12).
