Help me Mammas, My little one is now 11 weeks. Full on formula. Her birth weight was 6 pound 3 ounces. And now she is 8 pound 7 ounces, she takes 2 oz in every 2-3 hours.Her weight gain is very slow that's why her ped suggested us to add more formula and oatmeal ( 1 tspn per ounce) in her bottle. And apple juce for constipition.I read that we should not give cereal to baby at least until 4 month. What should i do? Am i alone? Do u have any experience like that? Help me plz
