Just thought I would post cause I can

I know it doeant really relate to the OP's question

However I am always getting now a days " wow, now that's a gap "

My DD is going to be 4 months of 21 when the twins are born - then of course there will be no gap between the twinnies

My sister and I are 12 years apart, and we are really close. So at different times in your childrens lives, they will be close, if you have a big gap or little gap .
