I heard this saying,that if you don't breastfeed as much as you can...Baby won't grow up to be close to you. Is it true?

This is certainly not true. If this is true, then how would one expect the father to bond closely with his child? While breastfeeding offers an opportunity for mother to bond with the baby given the intimate contact (literally), it is not the only way for bonding. What would truly help foster a strong bond is the love, care and concern expressed to the child.
