Exactly! Those exercises are amazing for the baby! Everything that we eat can impact them.. try to avoid the typical gas causing foods (flatulent): Cow’s Milk, Beans, Brócoli, Brussel Sprouts, Cabbage, etc.
I think at that age too they're learning to coordinate their muscles and understand the sensations around passing a bowel motion, I think its called grunting baby syndrome, they will learn in time, i have read that the baby might look like they're in pain but the crying is to try to increase the abdominal pressure to get poos and gas out not necessity from pain - but if you're worried always go check with a gp The tummy massage and bicycles are a nice idea, and reassurance and comfort when she's having a tough time
Ive had babies with both colic and reflux and yours sounds more like colic or gas pains. With reflux its not just a normal spit up. Milk can sometimes come up like an adult would vomit, with force and may not necessarily cause discomfort or pain. My current has reflux and he's barely ever cried with it and his sister was colicky and would cry non stop all the time
Sounds like gas. My son had terrible gas for months. Crying makes it worse. Try to catch when she passes gas and gently push on her tummy to get a little extra out. Try different formulas if you use one. Burp mid-feed instead of just at the end.
It could also be gas! Around that time frame my little one started having horrible issues with gas. Our midwife recommended doing little bicycle kicks and stomach massage. That did help a lot for the discomfort while I figured out which foods I was eating that was causing the gas.
