With Anneliese she was sleeping a lot more than usual, feeding less, and when i put her to bed at 8pm and woke her up at 6am, and her nappy was still dry, thats when i made the decision to take her in. You just know when its gone on long enough and they need some help. Im here if you need me... i know how stressful it is, i remember when i had Xander and i was trying to figure out whether he needed to go to hospital, or it was just me being a neurotic mother... our little premmies are more susceptible, Allie and Pat had Bronchiolitis before their due dates, but Xander was 42+3 and he has it 3 times in his first year. Good luck
