My son is 6 weeks old. He suffering from constipation and trapped wind so he's often a bit whiny and crying. He's not saying settings for very long. He's on lactulose. I noticed tonight after settling him he was quite cold to the touch. I did is temperature with a Tommee Tippee thermometer. It came back at 31.1. I want to show whether I did it correctly so I will redo it. He's taking his feeds very well and apart from crying and screaming he is having good alert periods. I'm also what is best to do. I'm a first time Mum.
