The sleeping of my baby

Every family are dearly loved for their children, including me. But love will be cause another bad influence sometimes, when i picked my daughter up from my hometown before two weeks. maybe we have long time no see my daughter, we accompany with her once we got home everyday, she was also happy and vigorously. on one hand, we felt that she  was so sunshine than before, speak more, smile more on her face , we are so happy on it. on the other hand, we found that she was sleep late every day, even nearly 12 am, the biological clock was changed, it was no discipline every day. why was it caused ? searched on it and there were some reasons. so exciting on day time, lack of vitamin D. it was not adapted with new environment, and etc. Adjustment must to be start immediately. we need to change a proper way to love or care about my daughter. we hope that taking much time to care about her due to we are apart from two places. Love is no fault, but how to choose a appropriate way to express, it was a explore way, every children was the independent one in the world. i wish that my daughter can healthily and happily every day, even i still can not find a appropriate way to resolve the sleeping problem.
