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?

I don't agree with this. Babies who aren't breastfed will also be close to you. You being the mother has a great deal of bonding with the baby. You do not carry the baby in your tummy in vain. Whatever you say or do during pregnancy till the day they are born, they knows it. To me, it is the quality time you spent with the baby. They learn and pick up fast.
