4 is our target. We just had our first son and plan to have at least another son.

My family have 5 siblings - myself, sis, bro, bro, sis.
My husband family - husband, sis, sis

My husband always say that more children is better than less. Yes, supporting them in growing up is a tough process but will be worth it when you have more children coming home to you when you are old. If you only have 2 children, one go overseas, one married follow husband / wife. You are left with none. He also thinks it's a good idea to keep one baby at home, he does not see a age gap problem as he is very close to his youngest sis who is 11 years apart from him.

I am not sure if it's a good idea but we plan to have one every alternate year due to financial stability and let my body recuperate first.
