Toodler , milk allergy ?

So let me get into this My daughter just turned one

Since she was about a month old she would cry but she would cry so much i thought it was purple crying but she would always spit up milk I brought it attention to my doc n she told me I was over feeding . I told her I don’t think I am i already have a another kid bla bla bla

Through would this journey of her turning a year my daughter can NEVER go poop normally she would poop normally one day the. Get extremely constipated that I would have to help poop and it would her from being so backed up or a laxative

I done wte r prun and so forth

Fast forward to now I stopped giving her whole milk she take almond milk some days she’s okay other days she gets super backed up still that I have to help yet I’m not getting answers and it hurts her like she cry’s bloody hell when she’s able to push it out and I shit you not this shit it big lol like a grown man and it’s hard as hell that her butte hole bleeds
