With this reversal of roles, Mr Chua admitted he can now appreciate the role of a housewife better.
He said: "In our relationship, there is no one party who is superior to the other.
"Few men would like to do what I do. For it to work, you must believe in what you are doing and there needs to be trust between the spouses.
"If right now, I tell my wife that I would like to rejoin the workforce, she will support me in my decision.
"But now that I have grown so close to my children, it would be a huge sacrifice for me to go back to work and not be able to care for them.
"Unless the work is very challenging, I value my time with my children more than earning an income."
Wives: No respect lost for house hubbies
IF ONE party has to give up the job to look after the children, who should it be? Should it be dad or mum?
The New Paper on Sunday spoke to five couples who said that they have no issue with the man staying home to look after the children.
Most of them were more concerned with the loss of income of the party who needs to stay home, given the high cost of living in Singapore.
Typically, they felt that the person with the lower income should be the one to stay home.
Madam Jennifer Tan, 35, a sales executive, who gave birth to a son last week, said: "If the woman is earning $10,000 a month and the man is earning only $5,000 a month, then it makes more sense for the woman to keep her job to support the family."
Madam Tan's husband, Dr Andy Lee, 37, an entrepreneur, was asked if his wife would lose respect for him for if he stayed home to look after their baby.
Dr Lee replied: "I don't think so. If she wants me to be a stay-home dad, she can't say that I am worth nothing. I would have contributed by looking after our son."
Madam Tan said: "Why would I lose my respect for him? I feel it's a big sacrifice for the man to be able to do this. It just shows that he loves the family a lot."
Psychologist and family counsellor Richard Lim said there is a big jump in the number of wives who now earn the same, if not higher, salaries than their husbands. Often, this leads to unhappy situations at home.
Dr Lim said: "Regardless of what the initial arrangement was, it's hard for the man not to feel insecure. When the power shifts, it'll take for both the man and woman to adjust.
"Pride, which is an emotion, is not something that can be controlled."
Lawyer Steven Lam of JTJB has handled a few cases of wives divorcing their house husbands.
He said: "We're still an Asian society and the man is still regarded as the breadwinner. I have came across some cases where the woman had loved the man because of his status. And problems popped up when he became a house husband and she did not see him as capable as he used to be."
