Books with Accidental pregnancy trope where one mc is already a single parent

Hi yall are there any books out there that have a combination of accidental pregnancy and the single parent tropes? Like the fmc gets pregnant after like a one stand or something with the mmc and they kinda have to interact bc of the pregnancy however one of them either the fmc or mmc already has a child and are a single parent.

I'm fine with almost anything except historical romance
