Baby rice cereal

After trying the rice cereal for the first time, did anyone else notice their little eat way more?? We tried giving my son rice cereal yesterday and since then he won’t stop eating. He hasn’t slept more than an hour at a time when he usually sleeps 3-4 hours 😭 idk if he’s just cluster feeding or if the cereal just didn’t sit well in his tummy. Anyone have advice??
