Baby only wants mom

My baby turned 4 months and all of a sudden wants nothing to do with his dad. He refuses to let his dad put him to sleep and will cry his dead off until I pick him up. My husband has tried wearing a sweater of mine but baby can sense it and will not have it. I can tell my husband is a little sad..I’m also a little sad because there’s times when I just need a break but my husband can’t really help. Is anyone else experiencing this? I need some advice
