Red flags in new relationship?

My boyfriend (25, I’m 23) has said very early on in the relationship that he wants to be a “young parent”, meaning when his kid/s are our age, he’ll be in his 40s. We haven’t been together even a month yet and he’s already said I love you, and he’s brought up having a baby (within the next year)

Is this strange?

He doesn’t seem weird or anything. I usually have gut feelings about bad guys but he’s honestly the best person.

Can give more deets in the comments if there are any other questions.
