Since the birth of her child, Gu Xiaonuan has been separated from him and hasn't met him, which is why she can discuss so easily about how to make the child happier.
This isn't a judgment Gu Xiaonuan made lightly; she hopes she can decide what is best for the child based on facts.
Although Lu Xiao also caused quite a bit of trouble, Si Yuchen didn't take his appearance seriously at all.
Gu Xiaonuan and Si Yuchen had been together for some time, and if things were truly troublesome, Si Yuchen wouldn't be staying by her side every day like he is now.
Si Yuchen probably hasn't figured out how to deal with Lu Xiao yet, but it's alright for Gu Xiaonuan to throw the problem to him, right?
After all, they are married now, and as a couple, they must share weal and woe.
This applies to both Si Yuchen and Gu Xiaonuan.
Gu Xiaonuan can unreservedly accept Si Yuchen's kindness; if he intends to help resolve the issue, it would naturally be for the best.
