If you look at the message, it's a bit odd for being literal? "Wake up and make some money" on a Sunday? And, "I hear you had a baby" -- it's like they haven't talked to one another in awhile? Wouldn't a friend know if there was going to be a baby? Do you have any pets or is he mentoring anyone on a work project or in some other situation where the slang idea of "baby" would work? A new idea that could make money in the future and the "wake up and make some money" a message to "get going"? If your boyfriend is comfortable with your reading his texts, etc. I would ask him something simple like, "what is John talking about?" If it is a real baby, he'll have trouble coming up with a different scenario as his focus will be on not seeing pink elephants and that's all he will see
