My sweet girl BMs keep slowing way down

lots of pushing with no results.
She is 7 1/2 months. I make all her food. Mill oatmeal, puree sweet potatos, peas, zuchini, and pears. That's all she's had other than the occational brown rice and banana once or twice but she doesn't like it. Oh and she's breastfed. I have been trying to get her to take water + pear juice from a sippy cup but I'm not sure how much she swollows and how much ends up on her bib

She only gets solids twice a day about 2oz each feeding.
She got way stopped up a couple weeks ago so I stopped all solids until she was moving again. I started her back and it seems like when she had oatmeal she got slowed again, which just seems so bizzare to me because that's what I eat to help me go!
Any ideas or suggestions?
