My 奶奶 haven't do anything after I 生完bb.
But my mother told me don't wash the hair. But actually, I wash my hairs every 2 days, as my BB 臍帶 have some problems and need to go to 健康院 every 1-2 days, and it's Jul. So everytime I back from 健康院 I will also wash my hair and take a bath.
As I don't want to take the germs from 健康院 and to the BB. You know it's hard to don't touch the hairs. I always think if I don't wash the hair and touch the hair and touch the BB again.....
