I could do it on the 1st day. The nurse let me breastfeed the baby very soon after I delivered him. If you want to breastfeed your baby successfully, you must try not to feed your baby formula, unless it's really necessary. Even if you need to feed formula, see if you can do spoon feed. Normally, your milk may not come until the 2nd or 3rd day. To speed up the process, you can try to drink fresh squid + fish soup. It's v. efficient. Last but not least, sleep more!
