My older two are alot like that. They have always gotten along so great! They act alot like twins! Now, if I could just get the younger two to do the same! They are either happy together or at each others throat! I don't know if it is the fact the first two are boy/girl and the last boy/boy or if it is just their personalities.....lol
These kind of post really remind me of the reasons for staying home with those sweet babies. They grow up so fast...but you get to be a part of every moment! So sweet.
