Newborn awake in evenings

Hello! My 2-week old newborn has been pretty good at waking for feeds every 2.5 hours, keeping to 45 minutes wake windows and sleeping for most parts of the day, EXCEPT between 4-8pm everyday where he usually stays awake, is a little bit more fussy and wants to be carried more. He doesn't show any sleep cues (no yawning / closing eyes) and does frequent small feeds during this period of time. Is this normal? Have you done anything differently to your baby's routine if you're experiencing the same? 🙏
