How does a newborn impact on a family?

Parenthood is NOT for the faint of heart! It is draining in every way. An dalso VERY rewarding. All I can say is, having all these details you've asked is good, but just be ready for the ride of your life, many friends won't get it, before having kids you just do not get it. The first couple/few months are sometimes hell, but it will all seem normal eventaully. A crazy normal! It's beautiful...
