我家宝宝不会哭----分享在美国养孩子的妈妈经

我在美国生了两个孩子，生育前后都有培训班，家庭医生每次洗脑让我受益匪浅，我的两个宝宝在婴儿时期乖巧得好像家里没有小婴儿，我甚至疑心她们会不会哭？如今外婆常拿这句傻话笑我。回国后看到朋友或邻居们被小祖宗折磨得精疲力竭，我遇到一个就会分享妈妈经，很没效率，想着将妈妈经写下来或许会帮到手忙脚乱、身心疲惫的年轻爸爸妈妈。再次感谢南加州着名的儿科医生JANE GU，这几年在她的指导下学到很多一辈子都受益的育儿宝典。

This will be an ongoing command until the process is finished so open another shell/terminal window, log in without a password:

$ mysql -u root

Start MySQL

sudo /usr/local/mysql/support-files/mysql.server start
