My 5-month-old baby used to pass stool 5–6 times daily after birth. A doctor gave digestion medicine, but there was no big improvement. After the 2nd vaccination (at 2 months), stool frequency reduced to once every 6–7 days with normal consistency. But after the 4th vaccination (at 5 months), the stool pattern changed again. The baby started passing stool 4–5 times daily, sometimes just staining the diaper. The stool looked slightly frothy at first. Around the same time, the baby also started sucking fingers frequently. dr suggest Novozymina, Z&D, and OFM-DS. Frothy stool stopped, but frequent stooling continues. Baby is active, feeding well, and has no fever or dehydration. We want to know if this is normal or if any further check-up is needed.
