wenwen: My mum told me that too. But MIL say buay sai. I also bo bian. Then Hubby say this is my first pregnancy, better be safe then sorry. I also cannot move the bed, so I "make-do" ba.
BB: I think I will ask my hubby to convince my MIL to at least, bring the mattress to the floor. Or else, need lots of pillow and bolsters to "round" them up when they sleep on the bed.
