Baby freakin hibernating

Kyleigh • It's a boy!🌱🍼🐻 Born: 2•17•16
I've had to wake him up for each feeding, he will sleep over 4 hours if I let him (well that was overnight when I do, but still). Is this normal? He is only awake when I change his diaper and move him around to breastfeed, and he just passes the f out. I mean like, thank god I can finally get some housework done, but is this normal? Not worried just wondering. FTM and all. 🐻💤
