Hey dear good morning. Dear solids or semi solids s not safe for under 6 months babies. As babies digestive system is weak ND baby cannot digest any solids or semi solids before 6 months.so till 6 months give only breastfeeding milk to baby ..if ur breastfeeding milk s not sufficient take healthy diet as take shatavar churn wit milk ,sooji,daliya,green vegetables, fresh fruits,nuts ,oats,ragi in diet too .try it until bf increase take help of formula milk as lactogen or Nan pro or Similac all are safe .try it
