I just woke up next to my 6-week-old in bed and noticed that he is HOT to the touch. I took his rectal temp, and it's 101.5. Yesterday and again this morning he's been having very watery stools. One diaper was FULL of what looked like bright yellow water. He's also been congested and coughing for about a week and a half. We took him to see the pediatrician last week for these things, and he said it appeared to be allergies. The congestion & cough have both gotten worse in the past day or so. He's actually been coughing so hard, he'll throw up if he's just eaten. (And he's not normally a spitty baby.) He is still nursing well. Since it's Labor Day weekend, we wouldn't be able to see a doctor until Tuesday morning. Would you go into the ER for these symptoms in a 6-week-old?
