My 7 year old doughter came to me saying it feels like my heart is not pumping I kinda laughed at first, but then placed my hand over her heart and noticed it was rapid; I kinda panicked but did not show her I was. So I had her lay with me and told her to take slow deep breaths as I asked her questions to try to dis tract her from worrying about her heart it slowly went back to normal. This is the second time she has came to me with this problem, but than last night she came to me with a new problem; her legs and feet were hurting, I was wondering know if she may have problems with her heart and blood not flowing well, she doesn t drink often but when she does she loves water. She does not drink pop. But one of the days that she had a rapid heart beat she was with her grandam s and she did drink pop so I assumed it was cause she flooded her system with sager and she was not used to it.
