my 7month old is very cranky..i do not understand what is the problem with her..even after feeding and giving her food n all she constantly cries..she never plays herself for more than 2 mins..she will cry and shout on drop of her toys from her hand and then I have to pick her up and roam around. then again when I keep her down she is ok for 2mins and then again starts crying..I get very exhausted as I dont have any helper at home..I have been getting back and lower back pains and its becoming very difficult for me to handle her. I have seen other babies playing after feed but my lo cries whole day..what do I do..its not that she is not well..she has formed the habbit of crying
