Their relationship would likely become more centered around the baby. They would have to make decisions together for the baby's well - being.
Well, at first, it might be a bit of a struggle. There could be arguments over who does what more. But as they figure things out, they would realize how much they need each other. The baby would be a symbol of their love and commitment, and they would work hard to make their relationship work for the sake of their child. They would also find new things to love about each other as they see how the other interacts with the baby.
Their relationship could develop through shared hobbies. For instance, if Penny starts to show more interest in Leonard's scientific work, it can bring them closer. They can have deep conversations about his research, and Leonard can teach her new things.
In this fanfiction, perhaps the baby brings a new sense of purpose to Penny and Leonard's relationship. They might have to learn to communicate better as they have different parenting styles. For example, Penny might be more laid - back while Leonard could be more cautious. The story could also involve their family members' reactions to the new addition to the family. Their parents might visit and give all sorts of advice, which could create some comical or heartwarming scenes.
Howard and Bernadette would be great godparents. They are good friends with Penny and Leonard, and they already have experience with raising a child. Howard could teach the baby some engineering tricks, while Bernadette could offer motherly advice.
A popular story could be about how they first met and the initial attraction. Leonard was smitten with Penny right from the start, and Penny gradually saw the good in Leonard. Their first date, which was filled with nervousness and some awkward moments, was a key part of their relationship's origin. Also, their story of living together brought new challenges and joys. They had to learn to share space, deal with each other's habits, and that was an important aspect of their relationship development.
In fanfiction, Leonard and Penny might have a laid - back parenting style. Given Leonard's somewhat nerdy yet kind nature and Penny's more outgoing and fun - loving personality, they could balance each other well. For example, Leonard might be the one to help with homework and encourage academic pursuits, while Penny would be all about taking the baby out for adventures and teaching them to be social.
Leonard would probably be shocked at first. If he's in a good place in his own relationship, he might be more accepting. But if not, it could stir up old feelings of jealousy. However, in the long run, depending on how Sheldon and Penny handle it, Leonard could come to accept it and they could all find a new normal in their friendship group. For example, if Sheldon and Penny are happy together, Leonard might see that and be happy for them despite the initial shock.
