DH is one of 3 and i asked him what he thought.

He said that they grew up playing closer then most kids where there was only 2 siblings, they are all still fairly close now as well. He is the eldest, his sister and bother are a bit closer these days but thats mainly because they live within 30 mins of each other, where as DH lives over 15 hours and a whole state away.

Our kids are all close in age (11 months between #1 and #2, then 15 months between #2 and #3). I know my first two are close friendship wise, play great and share a real bond. Im sure their brother will fit in nicely with them as he grows up as well
