Accidentally left piece of bread in crib

EDIT: no we don’t have a rat or pest problem and never have

Husband is furious at me. Last night, while I was up exhaustedly soothing our 4.5 month old to sleep, I was eating a piece of bread. I guess some of it must have fallen on my clothes without me realizing and when I transferred her to the crib, a fairly large chunk of bread must have fallen in without me noticing since it was in the dark. When we woke up, my husband was yelling at me and telling me I did a terrible thing and am doing a terrible job bc it could attract rats near our baby. I feel so bad and have been beating myself up all day- how could I let this happen?
