Angel baby / demon baby?
My first baby is a joy - quiet, calm, sweet, fun-loving. After I got pregnant with my second a relative said,"get ready, out of any two siblings one is always the high-maintenance, difficult child." I see a lot of posts on this subreddit saying that one of their children is so sweet and the other is unexpectedly a handful - eg, temper tantrums, doesn't sleep, whiny, etc. Do you think of this angel baby / demon baby theory? Does anyone have two kids who are lovely?
