Being parent of three, this is important for us to watch out. The following useful extract is from here: http://today.msnbc.msn.com/id/14335112
“Yes, the “Middle Child Syndrome” is very real. Middle kids bemoan their fate as being ignored and often grow resentful of all the parental attention given to the oldest and the baby of the family, and feel short-shifted. Three kids triangulate sibling relationships, with one child at any given point feeling like the odd man out from the chumminess of the other two. .."
"The middle child usually has to fight harder for the attention of their parents and therefore crave the family spotlight. They may feel that they do not get as much praise as the older children for simple firsts like tying a shoe or riding a bike. Those things just become expected.”
"Having a third child also means a changed parenting style. Here you must move from one-on-one to a zone defense. You no longer have one parent per child and everyone gets less individual time and attention. You have to double-up and the logistics get more complex."
"With three kids comes three times the chaos! Older children have to become more independent, which often involves being more adventuresome and more destructive. Suddenly you are feeding the baby and have sofa divers on your hands! Older siblings grow closer and develop as collaborators and co-conspirators."
