EBF hasn’t pooped

It’s been almost 2 days since my son last pooped, he usually goes daily but has skipped one day once. He’s EBF and is having plenty of pee diapers, he acts happy and completely normal. I know they say EBF babies can go awhile but it’s not normal for him and I’ve also heard that isn’t true and they should be going everyday regardless. He’s 4 months old.
