Just wanted to let you know your not alone! My 7 month old son is similar. He used to sleep a long block but not anymore. He was waking a lot with wind pains from solids, I thought he was teething but no teeth yet, and he's starting to look more like crawling...which disrupts sleep as well. The last few nights he's been a bit better, maybe because I cut out yoghurt or maybe unrelated! I just keep thinking its a phase that will pass!
