My yan yan came to our house end of June, even at end of Sept, my 2 kids (19 months and 2 1/2 years old girls) did not like her to bath them. One day, I found that my 19 mths daughter was standing in the water and crying, then, I found out that the water was too hot. I scolded my maid and asked her to make sure the water temperature is appropriate.
Besides, my 2 girls also did not like to play with my maid even my maid have been here for 3 months, what I observed was that my maid seldom played with them at that time, she only in touch with them when she had to, e.g. feeding time and bathing time. Other than that they have no interaction. I gave my maid a serious warning at that moment and ask her to figure out how to improve her relationship with my kids, otherwise, I cannot use her any more, then, she started to play with me more and I asked her to smile more when she is facing my girls. Now, my girls are willing to play with her.
However, talking about bathing, even though my 2 girls are willing to take bath now, but the water temperature is still not right, sometimes hot, sometimes warm, winter is coming, i am afraid my girls will get cold. :-( Lucikly, I am a full time mum, I can monitor closely.
