Normally, core body temperature is low in the morning and increases by few degree by the evening. So, a fever that was slight during the day can easliy spike by the night. Additionally, cortisol releases as a response to infection which is believed to be a protective mechanism against over activation of inflammatory system in the body. During night time, this protective mechanism is missed due to low cortisol levels and fever increases due to activation of inflammatory system.

My baby is 64 days old and sleeps through the night from 11 pm to 6 am without waking for feeds. His last feed is around 10:30 pm. During the day, he feeds on demand and stays active with good urine output, though he poops every alternate day. We're doing mixed feeding mostly pumped milk with formula only when needed. He had a lip and tongue tie release surgery 10 days ago and takes about 7-9 feeds per day. Should I wake him at night to feed or is it okay to let him sleep since he's gaining well and active during the day
