Well, I know of at least one episode where María's pregnant. This is the episode where she has a food craving that can't be satisfied cause she doesn't know what she wants until Snuffy hits it right on thenail. He suggests to María that she should drink some coconut milk, which is hexactly what she wanted being from the tropical nation of Puerto Rico. When she asks for some, Snuffy says that he has some coconuts that his grandmother sent him from her home in Hawaii. And then we see Snuffy's Grandmother knocking down the palm tree to get the coconuts. There might be other episodes featuring María's pregnancy, but I can't think of them. Hope this helps and have a good day.
