The best advice I can give you is to throw all clocks, watches, and guidelines righ tout hte window.
Nurse when hes hungry. Hes hungry when he smacks his lips, sucks his fingers, etc. Right now he may be crying simply b/c hes being laid down. Which is normal. They spent 100% of their time right next to you, feeling your body heat, hearing your heartbeat, and now, evne if you hold htem 90% of the time, thats a huge drop!
So - keep him close, skin to skin when possible, nurse on demand, sometimes htis will be every hour, sometimes this will be ever 10 minutes, and if youre lucky in the first 6 weeks youll get a few hours stretch now & again
Dont worry about spoiling him yet, he needs your body heat & heartbeat & touch and the reassurance that youre there as much as he needs food & oxygen at this age.
Baby slings & carriers are life savers at this point b/c they can free up your arms and allow you to do essential things like eat & pee

All the rest can pile up for a few more weeks, and itll be ok - or take the time when DH gets home to take care of the things that eat at you. But for now- cuddle up on the couch, readjust expectations, nurse him as long as he wants to nurse, switching sides only if he still acts hungry & is acting like he finished one side. Otherwise theres really no "need" to do 10 mins or 20 mins or even to nurse on both sides at one session. Many moms nurse on one side for one feeding, switch sides for the next feeding, and some even will nurse off one side for 2 hours (however many nursing sessions that ends up being), and 2 hours from the next one.
This is also a good way of ensureing that they get plenty of hindmilk - the fatty part of the milk that fills them up
Youre doing good, but those first 6 weeks can be challenging as you settle into a routine, are still learning your baby's cues, and adjusting to life (and how to let go of expectations & chores around the house lol).
Hang in there, it DOES get better. Hell eventually let you lay him down, sleep on his own, be able to let you know when hes truly hungry, and it all will just flow smoothly

I just wanted to add that judging by his age youve hit a 3 week growth spurt. Its normal for him to nurse a lot more often for a few days, and then itll resume a little more normal, and youll likely hit another at 6 weeks, 3 months, and 6 months (give or take).
