Spitting up

Ka

My One month old has been spitting up almost every time he eats since last night (EBF with bottle Periodically). I’ve checked his temp a few times and it has been normal. I’ve been keeping him elevated thinking it’s reflux but he still ends up spitting up quite a bit after he eats.

He also isn’t taking naps like he normally does. Growth spurt? Some sort of regression?

Anyone else have this problem? FTM not sure what all this could mean or be.

*I’ve had no dairy.
