Heres the context quoted from the source.

Feeling his baby bump getting bigger, Twilight insists that she and Mr. Baldwin go shopping in Ponyville to look for some maternity clothes so he wont stretch out his teacher outfits.

As the hours go by and Mr. Baldwin feels a lot more relaxed in with his pregnant belly under a good, stretched shirt, he and Twilight talk about what to do once he eventually does give birth.

Baldwin tells her that he feels more confident that he will make a wonderful mother/father to his future baby, knowing he has friends that will aid him whenever he needs it.

And he especially has Twilight, who has been helping him since their first night hanging out together. He tells her that shes mostly the reason he doesnt feel terrified about caring for his child.

He tells her that if he has a baby girlhe hopes shes just like Twilight.

Twilight, of course, is surprised by this, as well as touched. Shes even more astonished when Baldwin tells her that he might name his future daughter after her, or some name just as beautiful as Twilight Sparkle.
