My 16 month old son has always been an excellent sleeper and is always happy to go into his cot for a sleep. Last Monday he was taken to hospital with a viral infection and has since developed a secondary ear infection and is on antibiotics. Since the hospital visit he screams and cries whenever I take him anywhere near his cot and will only fall asleep on the couch with us. Is this just because he is sick and will he go back to normal soon????
