Practice #1

One of my friends called me to arrange have a playdate for our kids.
She has a small pool in on the deck. The three kids were excited to play in the pool at first, they seemed to be getting tired, and then they were frustrated to with each other.
I understood that it was difficult for an 8 years old boy was hard to play with a 4 years old girl and a 5 years old boy.
Suddenly, my friend recommended that I should me to have second kid. Me and My husband and I don't want to have more kids. I said to told her that if we had a baby soon, there would will be a 6 years old gap between ***(my son's name) and a baby. She said it would be no big deal to them someday.
I am not sure it would be no problem to them.
