Anyone else having a baby going through a possible growth spurt? And how are you dealing?

Basically my 5 week old all of a sudden switched his sleeping habits (he now takes more..and longer..naps throughout the day and will get super fussy and will not go to bed without a fight at night). His eating has increased for most feedings (eating up to 5oz every 3 hours) but will then cluster feed 2-3oz every 1-2 hours. There is very little spit up so I know he's just that hungry. Now the feedings I can handle because I bf then feed him via ebf (and if need be formula) so I know he's getting plenty of food, but it's his sleep schedule that's making me 😠😧😩😭. This has happened for the past 2 days/nights so I'm hoping it will not last forever, but I'm starting back at work tomorrow and my husband **love him but** is no help.

I was trying to figure out if this was just a growth spurt phase, which I hope it is, and if so I hope it doesn't last long. Any advice?
