A lot of sleeping

My baby is 6 weeks 6 days old.

He is nearing to his Leap 2 or growth spurt as it is.

It had been like a week since it was hardly impossible for him to sleep during day .it was 10 to 20 mints sleep.at night he slept well 7 to 6 hours

Last night he was extra fussy slept at 3 30 am and slept for 9 hours straight.

Than i cleaned him changed his nappies and he fed for 7 mintues n now he slept again.

Is this normal mommies'?

He hasn't slept so much til now.

Oh n he had his needle on the 7th July.

His weight,pee n poo r all good.

Anyones LO sleeping so much?
