Does this sound OK for a 20 week olds food/milk intake?

Have you talked to your doctor about it? My doctor said no juice until 6 months, and not to give a second solid meal in a day before 5 months. my daughter is also 20 weeks and she is drinking about 36-40 oz of milk a day and 2 tablespoons of cereal/fruit/veggies in one meal. My daughter also started solids very early on the advice of her pediatrician - I would just double check with your pediatrician since (s)he knows your child better than anyone.
