Thanks for your query.
1/-Nan-1 is the formula for babies from birth to 6 months & the Nan-2 is follow-on formula to meet nutritional needs of 6-12 month olds.
2/- Cow milk is not recommended as a main drink or food in the first year of life as :
* Young infants cannot digest cow’s milk as completely or easily as they digest formula.
* Also, cow’s milk contains high concentrations of protein and minerals, which can stress a newborn’s immature kidneys and cause severe illness at times of heat stress, fever, or diarrhea. * It may even cause iron-deficiency anemia in some babies, since cow’s milk protein can irritate the lining of the stomach and intestine, leading to loss of blood into the stools. Also it is a poor source of iron.
3/-In general solids are best started around 6 months of age.
Hope you find the information useful.

Hi,

Thank you for your query on Healthcare Magic.

Nan 1 and Nan 2 are infant milk formulas.

Nan 1 is given during the first 6 months of life when there is no breastfeeding is not available for the baby.

Nan 2 is given from 6 months onwards as a substitute for breast milk.

The 1 and 2 formulas are made depending on the digestive capabilities of various components of milk of an infant depending on his or her gut maturation as the age grows.

I advise you not to introduce any cow milk products below the age of 1 year as it may lead to colic, indigestion, and cow milk allergy with allergic tendency later in the life.

And infant solid foods are introduced from the age of 6 months and not from the age of 6 weeks (hope you wrote 6 weeks mistakently).

Nothing to worry, the quantity of their milk intake depends on their hunger and the volume of their stomach and their alertness at that time.

Hope I have answered your query.

Regards.
