My Yan is just the 4th day, this morning I heard her 打"乞chi". I asked her if she is sick, she said she's OK. Since I'm also sick this week, I put on mask all the time. Then I seriously told her, must consult Dr. even 小小, and must put on mask(just like me).
One thing to remind you, must teach them and watching them when taking medicine. They may have 0 concept of doing this. Let them know the importance to take medicine pormptly and properly, hope them can do the same way to our BB.
