Our 10-year-old son was making a card for his aunt on Sunday, and he didn’t know exactly what to say. So we Googled “Poems for aunt” and found this lovely website called FamilyFriendsPoems.com, a treasure trove of homespun verse to use when celebrating special occasions with family members and friends.
The site also has “I’m sorry” poems and poems that address loss and hardship. You can always adapt and rewrite other people’s poems to suit your needs. The site currently boasts a lot of Mother’s Day poems on their homepage, so you might want to have a look.
