Weaning was, for us, the only thing that helped Maia's reflux. Even today, at almost a year old, she still needs to have something solid in her tummy to keep her milk down. My pediatrician recommended that we put rice cereal in her last bottle of the day starting at 2months. I didn't feel comfortable, so I waited until she was almost 3 months - she kept waking up choking on her spit up, and it was scary. Sure enough, she stopped spitting up during the night when we gave her the rice in her bottle. We didn't give her any other solids or spoon feed her until she was between 5 and 6 months though (it was quite the debate - here we wait until 6 months, but in my OH's country, it's 5 months).
I noticed right away a huge difference in the amount of spit up and discomfort. Maybe it doesn't work for everyone, but it really helped us!
