I'm having the worst problem with my grandmother

. She worked for DHR,child services for a long time(so of course she knows EVERYTHING ABOUT CHILDREN AND BEHAVIOR). Anyway....she(her and my grandfather.who is just as gulity of spoiling every grandbaby they've ever had) keeps my 18month old daughter in the evenings after daycare(i work from 7am-7pm)I just went to drop her off and she starts screaming for me to pick her up and just throwing this tantrum.......Ive been trying not to give into these tantrums because she knows what she is doing....IF SHE CRIES....WE WILL PICK HER UP....well ...i'm tired of carrying her..
My grandmother proceeds to say"well, they only cry for a reason, she needs to be loved and held..she knows mom is leaving again"
This may not really sound that bad to you all...but i'm telling you .. everytime i try to lay down the rules....grandma has an answer.....All they do is spoil her and ruin everything that i'm trying to do...I'm trying to get her off the pacifier...she went two days without it...slept and everything...i get to grandma's and there she is with the passie again. i'm tired of it...and my grandmother is so **** sensitive that she starts crying if i try to tell her something different than what shes doing
ITS MY DAUGHTER!!!!!!! she tries to guilt trip and make me feel like i'm not there enough for her....well you know what....maybe i'm not./..but i have to work the hours that i do to provide for her---and to make a better life for her than what i had....i want my daughter to have the best things in life.....okay i'm ranting...........i think i might start leaving work a little earlier-and pick her up from daycare-and not go to grandmas house everyday.....is that wrong?
