My pediatrician just whipped through his rec'd about starting cereal, my head is spinning. I know I start with rice cereal 1tbsp rice/4-5tbsp of formula (or in my chunky monkey's case water) just by following the box...but how do I know when to go up to more cereal, then to multiple times a day and when to try oatmeal and/or barley?? I am so confused.
