Short spacing between children healthy or not?

I'm not sure how the author of this article is doing their math but the next royal baby would be spaced nearly two years apart from his or her older brother Prince George.

The average between my children is about two year. However, we have them as close as 14.5 months and 18 months. I have had no ill affect from the short spacing. So I am going to beg to differ and say every woman and family's situation will be different. We do what we feel is right and sometimes God has other plans.

So what is your take, is Short spacing between children healthy or not?
