Sleep for 3 month old

[Kiran25]

Hello Mums

I am newish mum to a little boy. He turned 3 months today .. Whoohoooooo

Was wondering how much sleep does he need at night/Day ?? If he sleeps thru like for 6-7 hours without a feed , shall i let him.

Would that be at noght or in the day?? If it's in the night - that's great!!
