Robby had his 4 month appointment on Tuesday. Doctor says go ahead on food start with cereal. The two times I have given it to him he ate it fine super excited. But hours after was super fussy and refusing sleep or eat. Just a mess. I'm not sure if it's just discomfort from shots. Not sure if it's the cereal. I suddenly am hearing he shouldn't eat u til 6 months. Why are we not given a manual? Lol
