I suspect that you are giving cow milk instead of breastfeeding. Or maybe mix feeding. Cow's milk cause allergy and anemia.
I also suspect that you are not giving proper food from 6 months of age
I also suspect that you are not giving
vitamin D
I also suspect that you are not maintaining growth chart of the baby.
Details given by you are not enough so I would suggest you to consult a pediatrician
Next Steps
