the cereal is thick, a baby that young could choke on the cereal. always ask you babies doctor about giving her other foods besides formula.

If you want to give cereal before six months you give barley, it's easier on their stomachs, but never at 3 weeks

Do not give your 3 week old nothong until at least 6 months old. If your 3 week old is not sleeping thrpugh the night swaddle your baby. It's so young that the baby doesn't know it yet. It takes patience and getting up every couple hours to feed the baby.
