Is age 4 “easier” than 3?

I know this is kind of a silly question as every stage has its difficulties. But my husband is having a very hard time (always has) dealing with crying (and now whining) that has increased during this third year of life. I’m finding it difficult to give our daughter a safe space when he is always telling her to stop crying and that she’s being a bad girl. I tell her crying is okay when we feel upset or sad but not if we’re just complaining about something. And when my husband is like “no crying is not okay! Tell her it’s not okay!” I’m like umm she’s three. When I tell him that she’s three and that it’s developmentally appropriate (and we are supposed to be teaching her to cope and regulate her emotions) he seems to think its BS and she’s being a brat and that she’ll always be this way unless I teach her to submit. So does the emotional roller coaster get less dramatic at 4 years old?? Or is this life forever?
