I haven't watched today's but as per yesterday's episode, there's nothing wrong with refering to the baby as a boy; it's human nature to refer to the third person as he. Let me give you a real life example. I was in the interview and I was asked the most famous question that every recruiter loves to ask: how do you handle stress or when you have too much on your table? While answering the question, I kept on referring the engineers on my team as "he", even though there are "she" engineers too on my team. It's human nature to refer to the third person as "he". Had Suhana said, in clear words, that she wants a boy, then yes you're right - why always a boy and not a girl?! But because she didn't say it, I dont think referring to the baby as a boy is entirely wrong.
