What concern does the narrator introduce in paragraph 1?

The narrator notes that she only had "two brothers" to worry about.

The old man first visited our house when I was five, in 1933. At that time, I had only two brothers to worry about. Kiam and Jung were then ten and seven years old. Sekky was not yet born, though he was on his way. Grandmother, or Poh-Poh, was going regularly to our family Tong Association Temple on Pender Street to pray for a boy.
