They might talk about their day. For example, Howard could share his experiences at work, like any new projects he's involved in or funny incidents with his colleagues. Bernadette might talk about her research or any meetings she had.
Howard and Bernadette had a wonderful bedtime routine. Every night, they would first make sure their pets were all settled. Then, they'd get into their warm pajamas. On this particular night, Howard was a bit excited because he had found an old comic book from his childhood earlier that day. He told Bernadette all about it as they lay in bed. Bernadette listened intently, even though she was a bit tired. She loved seeing Howard so enthusiastic. After he finished, they cuddled up close. Bernadette started to sing a soft lullaby that she remembered from her own childhood. Howard felt so relaxed listening to her sweet voice, and soon, with the peace of their bedroom and the love between them, they both fell asleep.
Raj could be a great addition. He might be the nervous uncle who is always a bit afraid of holding the baby but tries his best. His attempts at babysitting could lead to some really funny situations, like accidentally mixing up the baby's formula with his coffee.
A great fanfiction idea might be that the baby shows an early interest in music, which is a bit of a surprise since neither Howard nor Bernadette are particularly musical. They then go on a journey of exploring the world of music with their baby, from buying little baby instruments to attending children's music concerts. It shows how they adapt to their baby's newfound interest and how it brings a new dimension to their family life.

Inside, there was a polar bear family. The bear cubs were playing. They welcomed Howard and shared their warm fur rugs with him. They also told him stories about how they survived in the icy world. Howard felt so comfortable and warm that he fell asleep listening to their stories.
