I had a relationship with a woman who had a 7 year old Daughter.   The little girl made me a hand-made birthday card for my birthday that she made with construction paper and crayon and glue and glitter.   Her Mother said she had spent 2 hours making the card for me.   I kept that card for many years afterwards, even though I broke up with the Mother.   Young kids can be pains in the asses, and they can also be sources of great joy, even if they are not your biological children.
