Baby eating less??

I noticed my 5 month old has been eating less.

He will drink 2 oz and then wait 30 minutes to an hour and drink another 2 oz.

He usually drinks his full 6 oz bottle. He’s been teething and already has two bottom teeth in. I noticed he wants to breastfeed more than drink from a bottle.

He doesn’t seem sick or uncomfortable and has over 6 wet diapers a day still. I heard that the oz go by weight and he should be drinking over 30 ounces in 24 hrs. Has anyone else noticed their little one drinking less milk? Comment!
