Dirty Diaper Counts

Alexa&Joe
We've noticed a decrease in the number of dirty diapers as our son has hit his 1 month mark. He went from having 5-6 dirties a day to now maybe having 1-2....sometimes none. He's having plenty of wet diapers so we don't think he's dehydrated and he farts a bunch too. Any thoughts or concerns that we might need to be having?
