My Baby has fibrous material almost like tomato in her stool

What is normal for your child usually depends on how old your baby is, whether she's breastfed or bottle-fed and whether she's started solids.

So maybe you could provide us with some more information?

 

Anyway when my sister’s baby have started with the solids we had few worries ourselves. We have found that her poos were affected by the foods she was eating. We were feeding her with pureed carrot and the next day contents of her nappy were bright orange. 

After some research we realized that it is possible that fiber-rich foods pass straight through your baby and end up in her nappy. This will change when she gets older and is able to digest fiber more efficiently but just in case that something is wrong consult with your doctor. It is way much better to be safe than sorry.
