you are not experiencing an unusual challenge. many babies at this age go through refusal. be patient maybe give him a break for a couple of days and then try it again. which fruits/veggies have you offered so far and are you making/buying them? the good news is that at this age the majority of calories will come from your baby's milk source (breastmilk/formula). your baby needs a minimum of 4 tablespoons of iron-fortified cereal in order to get enough iron to prevent the onset of anemia. when you reintroduce solids i would try to establish the rice or oatmeal cereal.
our son started eating rice cereal at 5 months and veggies/fruit at 6 months. he refuses the solids. any suggestions?
