By when can i start normal tetra packed milk for my baby?

I'd say it's better to wait till after baby turns 1 (one). Before that, all the nutrients baby need is available in breast milk and formula (which is produced to resemble breast milk). Some of the reasons to wait in terms of feeding baby tetra packed milk include: - Baby will be deprived of important nutrients, including iron, that breast milk and formula contains -- tetra packed milk might not contain as much - Your baby’s digestive system will not be able to handle all the proteins and sodium present in tetra packed milk http://www.beingtheparent.com/when-can-i-give-packaged-milk-to-my-baby/
