Bf wants me to meet his baby

So I’ve been with my boyfriend for 9 months and he has a 1 year old. He’s a teen parent and the child lives with the mother. Today over a text he said he wants me to meet the child. It was completely random, I didn’t say yes or no to it and i just changed the topic.

Also would i be considered a step-mother to the child or would marriage actually make it official. I’ve been kind of thinking of that the whole relationship lol.

Anyways I would want to meet his baby but idk if it’s too soon for that. Any advice ?
