Limbo = basically saying “we don’t know” - it’s not clearly defined, so where do they go? “we don’t know”/Limbo — BUT we believe in a loving God, so we believe they must be in heaven, but what God’s plan is for that, we don’t know. And here I’m talking specifically about unbaptized innocents.
Others believe in a wrathful God, so now what???
What any of us 'believe' probably has little effect on what actually is happening.
