I started my daughter on rice at 3 months little by little she loved it. Now shes 4 months and doesnt want it and starts to fuss when i give it to her. she doesnt like any of the baby foods.... she threw up peas one day! now she doesnt want her rice ceral her poop is thinner.. she went from 7 oz and rice each feeding (formula) to maybe 5 oz. with just a little. did i start her to soon? i dont know if shes teething or not?? shes learned to scream how do i stop that?
