Does anyone know if chicken purée sits longer in the stomach than fruit or vegetable purées??

My LO has had bananas and sweet potatoes but still wakes up 1-2 times in the night for a feeding.

Well last night I gave him a chicken and veggies purée and he slept from 8pm-5am! And he hasn’t done that in a longggg time!

My MIL said that usually fruits and vegetables usually go right threw you so that’s why I’m just wondering if anyone knows if chicken would sit in their stomach a little longer. Just curious!

I also switched from stage 1 food to stage 2 if that makes a difference!
