He is bottle feed, takes his feeds well and until 2 days ago was winding fine. Last night about 8 he starting crying in pain. I knew it was wind, it didn't go until 11ish. He was restless all night. Fine today then 4.30 started again. It's awful to see him in so much pain and so tidy. Could his be a one off? Or does this sounds like the start of colic?
