C is on amoxicillin for an infection. My great sleeper all of a sudden REFUSES to sleep unless she just passes out someplace other than her crib. Has anyone else had a hyperactivity reaction from amoxicillin? The doctor agreed to switch her antibiotic today just in case and I already asked them not to flavor it to avoid any food dye sensitivities that might be at play. Mama's TIRED. Tell me I'm not just grasping at straws!
