Sth can be used to tied bb in the chair! I bought one from 西田, $1xx, very useful. Just like a coat for bb to wear, but with 安全帶 to fix bb in a chair. can use at home and sometimes in restaurants outside (for chairs with back).
how come ur yun yun can be so free to switch on the TV without your permission? u should stop her and educate her ar. Just give her a good reason: you don't want your bb to watch TV or disturbed by TV!
