The baby has been defecating every seven or eight days since one week postpartum. Now at three months old, the stool is golden yellow with a bit of stickiness, and there is a lot of stool each time. Defecation is normal, with a slightly sour smell. The baby is breastfed and has been given probiotics many times without any effect. Water is given once a day in the afternoon, with ten milliliters each time. Is this normal? Is the baby constipated? Height and weight are normal, and breastfeeding is normal.
