My baby is 19 days old. I tried to breastfeed him for the first 3 days after he was born. From the 4th day onwards, we changed to feed him with Formula Milk and sometimes my expressed Breastmilk (if any). Am wondering is it too late if i want to direct latch him again? Am worried that i do not have enough milk for him as he can drink around 90ml to 110ml Formula Milk per feed.
