Youth rifle

Hello all, my son asked me to go hunting. Of course I am not going to tell him no, but I need to buy him his first rifle.

What kind of suggestions would you give?

He is 9 (will be 10 in july) and about average height for his age. 4 and a half feet tall.

Also I know this isn't the sub for it but if anyone has suggestions of a decent ground blind that fits 2 people and some gear like backpacks and chairs for michigan hunting I'd appreciate it.
