L.O.
this is normal in a breastfed baby. Breastfed babies do not get constipated - ever never. Breast milk is almost completely digested by the baby- there is little waste. He is fine- he doesnt need a suppositiory. When breast fed babies are very young they may have several bowel movements a day (one after every feeding is normal too.) but now that he is older- whatever he does is normal.. Do not worry he is fine.
My daughter was exclusively breastfed for 10 months. she was never ever constipated.
