Help with nap time

My baby is 4 months old pretty soon. He has an established night time routine now.. he is usually completely out by 9:30--10 if our night is going rough.. he'd fuss around 3:30 but usually stays asleep until 7am..

However, during the day, he will take at least 4 naps ranging from an hour to 3 sometimes. But this boy won't sleep unless I hold him. It doesn't matter how out he is, he wakes up and cries hysterically when I put him down. It doesn't matter if it's the bassinet or the crib-- he wakes up and cries.

I can't get anything done. Very rarely but I have to rush! 😪😪 I have tried almost everything and nothing is working.
