But may I know the reason why you have the 2nd child? For a more complete family?J Or just raised by your big kid? Indeed I've struggled for a long time to make such decision.
I am also eight years older than my sis. We share more common interests in reading and arts much more than my elder sis, who is just one year older than me.
So I don't think the number of years should be the decisive factor when considering whether to have the next child. The ultimate question is whether you can cope with the challenges of starting everything all over again after all these years.
