Is my baby on a growth spurt? Is it cluster feeding? Or have i got a greedy bum? I'm a ftm.

So my son is 8 days old he weighed 8lb 2 and a half Oz. On day 5 he got weighed and was 7lb 11oz.

He was taking 2oz of breast milk every two hours (by bottle) but I've noticed he doesn't seem fully satisfied after a feed. I mean he will settle, but with skin 2 skin.

So I researched more into it and it says if your baby is demanding more then give more so of course that's what I've done. He took 3oz at 8:00pm and finished at 8:15pm but then at 9:43pm he demanded more but only took 1oz and finished at 9:55pm then at 10:35 he took 2oz and finished at 10:48? Now hes fast asleep on my chest. This has only just started to happen. I'm a ftm so this is all new to me.
