My baby started to have constipation when he was 1 month old and I was told that because I stopped breastfeeding him too abruptly. Yet, the situation should improve after a month when his digestive system become more mature. However, my baby is three months now. My pediatrician suggests me to give him apple prune juice/OJ. And I read articles saying that these juices actually have some diahrrea effect. Yet, he still wouldn't poo straight after. His record high was not pooing for 3 days. However, he is going to his forth day this time. Any suggestions? Some people suggest me switch to Japan made formula.
