The reality of four

What does that sentence really mean?
I caught myself wondering what bedtime will be like with 4 children. Right now its quite organised with a routine... dinner, desert, milk, toilet then bed. No wavering unless a second bath is needed. I dont really remember it being different going from 2 to 3, although I guess the first couple of months takes some getting used to. I'm so excited to be having another baby. I wonder how he/she will fit into our family. I know the baby will bring more work, but also more love and giggles. I think its definately worth it, having another one, I mean, its so lovely watching them play and grow and learn. Even better when you see them develop friendships and love for each other. By this time next year that 4 children scenario will be a reality.
