My daughter is having cough, cold and blocking chest, recommend me some home remedies for her. She is 2.8 years old

In addition to what all the other parents suggested, i would also say that do the warm mustard oil massage for your child. you can use warm mustard oil to massage the chest, throat, back and soles of the feet. put on socks for your child and cover her with a comforter. this will retain her body heat and reduce cold and cough as well as clear her nose.
