For all intents and purpose non of my own kids ever knew it any different. As I said my oldest was under 2 when I started and she loved having a friend to play with while I was busy with our baby. My next two kids were born into the daycare. Right now my youngest is 18 years old and the only one still at home. She has special needs and fits in well with the toddler activities so it still works for me. When you have 4 kids it doesn't take much to have extra kids hanging around.
