de niño era aventurero. solía correr y jugar con mi abuela. fui a una guardería. me pondría vestidos pequeños. La entrada a la guardería era dulce.
thats what i would put. If you need any help with spanish i can help because im half spanish myself.
Explanation:
Mi abuelo es argentina is incorrect because abuelo means grandfather, who is obviously a male, and the adjective argentina is used to denote feminine gender because it ends with -a. Instead, if you want to correct this sentence, you should write the adjective in masculine form (ending with -o).
So, it should go like this:
Mi abuelo es argentino.
