My 4 month old has been battling a cold for the past 10 days. Some days are better than others, but he's extremely congested to the point where he's having trouble nursing at times and is also throwing up mucus and throwing up when he coughs. At his 4 month appointment on 4/1 he was 14.5 lbs. When my hubby took him to the doctors to make sure he didn't have anything more than a cold on 4/16, he was 14.7 lbs. He had been gaining an ounce a day between 3 and 4 months. Is this a normal result of his illness or do I worry? He has had some days of slowed appetite, but is otherwise hungry and eating.
Thank you for the perspective.
