PARANOIA

Hi. Im really worried. My baby is 10 days old today and he slept really soundly for 3hrs so we woke him up bcos as per google, babies will sleep between 2 to 3hrs only. We woke him up after 3hrs and breastfed him. Then after few mins like 3 or 4, he slept again, burped him then fed him with the other boob then slept again. He seemed full so we just put him right back to bed. Was it okay to wake him up?

And also if he is sleeping, he turns yellow but it will disappear once he is awake. We did expose him to sunlight since day 4. Should we be concerned?
