Am I doing something wrong?

Emma
Basically my daughter has been on solids for nearly 4 weeks now, but she is doing very solid poos. She seems to be constipated and she'll start crying with pain. 
She has 4-5 5oz bottles 
2 stage 1 solid meals 
And a sippy cup or 2 of water with a dash of juice a day.
Is it anything I'm giving or not giving her? And can anyone recommend anything to help her please
