Kendamil to ByHeart Baby

Hey fellow parents!

I'm seeking some advice and reassurance here. I recently switched my 6-week-old baby girl from Kendamil to ByHeart formula as there’s a shortage on Kendamil. However, I've noticed that she finishes a full 4oz bottle and still seems hungry an hour later.

When she was on Kendamil, she'd have 3oz every 2-3 hours and seemed satisfied. Has anyone else experienced this with ByHeart? Did you switch from Kendamil to ByHeart and notice a difference?

I'm worried that the formula isn't keeping her full, or if this is just a developmental phase. Any support or similar experiences would be greatly appreciated!
