Sorry to hear about your mess, my little one is a little smaller; just five months and I went though and am going though the same things at the moment. SAbout 10 days ago she started vomiting up some feeds during the day, usually the feeds which were just milk; sometimes straight away and at others up to 2 hours after. It seemed like the milk never even hit her stomach i.e. no curdeled milk. I could live with that but then she started puking up every night after her bottle. The general consensus was that there was nothing to worry about as she was thriving, pooh ok etc... I think the crawling certainly has something to do with it, I think he milk migh just be too light for lack of a better word. I have started thickening her night bottle with rice ( first time last night) and it worked, I am going to change to a thicker formula if this continues to be successful.
Give it a little time; try going back to a slower flow teat, that helped me to, perhaps limit physical activity straight after eating ( not relevant at night I know!!!!) if it does not get better obviously go see a doctor. I wa\s reluctant since it is normal for babies to throw up and I seem to be able to manage it at home plus they are all desperate to put babies on meds which i did not want. If it does not get better I will have to though.
