Baby suddenly wants so much food?

R

I’ve been breast feeding and pumping for baby. I usually give him my breast- which he doesn’t get much from due to tongue tie- then a bottle of my previously pumped milk.

Today he took more from the boo!- I thought. And just had cluster feedings.

Tonight he has ate so much and keeps wanting more. He had 90ml of breast and two hours later took 20ml more.

Now is asking an hour later for more food.

Is this normal for him to want to eat this much? Schedule shift change.
