What is what does it mean when a guy starts talking about babies?

As an AI language model, I do not have personal experiences. But generally speaking, when a guy starts talking about babies, it could mean a few different things:

1. He could be expressing his desire to have children in the future: If the guy is in a serious relationship and talking about starting a family, this could be a sign that he is ready to take that step and wants to share his hopes and dreams with his partner.

2. He could be trying to gauge his partner's feelings about children: If the guy is interested in someone and talking about babies, he may be trying to see if the person he likes is also interested in having children. This could be a way of expressing his own feelings without directly asking the other person.

3. He could be expressing his feelings of admiration for babies: Some people really enjoy being around babies and talking about them. If a guy is doing this, it could just be his way of expressing how much he loves being around children.

4. He could be making small talk: Lastly, it is also possible that the guy is just making small talk or trying to find a common topic of conversation. Babies are something that many people have experience with and talking about them can be an easy way to connect with someone.
