Dear cousin Sadie,My mom told me it's your birthday today. I kicked her in the stomach to let her know I heard which she thought meant I was jealous she was talking about another child, but in reality I'm really excited. I hear birthday parties are a fun time and I wish I could be at yours.
I'm glad you liked the vet kit
Here's a birthday card I'd send you if I had access to stamps and a mailbox.
I can't wait to meet you at Christmas. Or more technically, be in the same state as you. Hopefully we won't be meeting in person for a while.
