Second on the way- what to consider/prepare with the second that the first child didn’t bring up?

Hi all,I am a father of a lovely 2 (and a half) year old lively girl and my SO and I are in expecting our second early next year- yes a while to go.But the controlled excitement is bubbling- we are keeping calm since it’s very early still.My question was: I’ve heard the second brings challenges, issues, fun opportunities and things to consider that having just one didn’t?Please can you all impart some wisdom for me, my wife and as a couple we should consider and prepare...Thanks as always all! via /r/Parenting https://ift.tt/2Kyjjg6
