Around six months ago, we stopped breastfeeding my first child after my wife and I found out that my wife was 3 months pregnant.
In about 1 month my wife will give birth to our second child. At that time, my first child will be 20 months old.
We are planning to start to give breast milk to him again, because we still have 4 months to go until he is 24 months old. Is that ok? And also is it ok if we plan to breastfeed him for longer than 4 months? It means my first child will still be breastfed after he is older than 24 months old.
