DD 11 month has been on amoxcillian for 3 days for croup. She has never been a brilliant sleeper but has always gone off at 7 till at least 10 before waking. Since she has been amoxcillan she has halfed her daytime nap and just will not go to sleep, she doesnt seem tire. She is sat playing now!! Has anyone experienced this, please tell me its not a long term thing. She is also on nofedipine and asprin so I am wondering if this is reacting or something
