Yes definitely... Mother's milk has all the nutrients and immunity boosters that no other supplements can provide to your baby... I breastfeed my baby girl for almost 2.5 years and my baby girl immunity is very good.. she is 4years now and in these 4years I hardly visit doc for almost 3 times for fever... Not even cough and cold get to my baby girl.. only a mild cold but never went for doc for medication , only vicks vapourub works for me everytime... So I guess it is because I fed her 100percent breastfeed for the first year....

Yes its right n thats y whenever u choose formula milk fr baby just read its contents n prefer to buy fm which contains prebiotic in it.

Yes, breastfed babies immunity is higher then formula fed babies.

Yes! Breastfeed always good for babies. If your baby is less than one year, It's better to continue breastfeeding as long as possible, it has not any replacement.
