if I were you, and when the baby wakes up from their mahjong noise, I will bring the baby out to where they are playing the mahjong and purposely let his friends see the scene and make them aware that they are being as a noise nuisance and alr caused the baby to wake up from playing mahjong till so late. then hope they become auto and leave and next time will be paiseh to accept any gameplay from your hubs. they're so inconsiderate and buay 自动
