poor dd had a heel of a day yesterday, 2 doctor appointments and a hospital visit for a xray and blood work. she has the on comings of a ear infection and possibly early staged of pneumonia or bronchitis. they put her on zithromax and shes been soooo sleepy. she slept form 7:30 last night to 8:30 this morning then went down for another nap at 10 and is still sleeping. She was on zithromax 2 months ago for possible wooping cough but i dont remember her being so tired. can it make them sleepy?
