My DS is 14 weeks and 3 days old, he was 3.5 weeks early, so effectivley he is 11 weeks, he has normally gone to bed quite well at about 7.15 without to much fuss, however the last 3 nights he has screamed blue murder untill about 9pm, which is completly out of character. He did have colic but he is not arching his back etc for me to think this is it. I was just wondering if it could be a growth spurt and what are "typical" symptoms of this??
