My son, three months old & 14lbs, has a fever again today. Yesterday he had projectile vomited twice and had diarrhea. I took a cool shower with him so I could nurse him in the shower in hopes he’d keep it down, which he did, but being I’m sunburnt and only added heat to him I put him in his bath and let him hang out for about 30-45 minutes. We were out in the heat, but in the shade, for about 3 hours on Wednesday so I’ve kept him inside in the air conditioning and fans. Any idea on what I can do for him to keep this fever away? He’s still smiling and eating. So far today he hasn’t puked.
