If you have multiple kids and stay in a simple 4room HDB, how would you share their rooms? I happen to have 3 girls.

Hi, I have 3 girls as well. It depends on their age differences. If they are still young (below 10) the first 2 elder girls are sleeping together. The youngest would be with me. As they grow older, I'll have them all in a room and the other room be converted to a study room.
