When my daughter was a baby we gave her biogaia. She was having a lot of belly cramps/gas and would spit her milk up. After about 2-3 weeks we saw improvements. Try to burp baby a few times during feeds. For example if baby has 4oz each meal try to burp every 2. I also tried to use it with my son but it didn't work for him.
Helped my daughter! And cutting out processed meat (if you're breastfeeding)
We use cocyntal drops from Boiron
I took mine to a pediatrician and he needed to be on medication for 6 months. I'd take him to the doc personally
We tried Biogaia but unfortunately didn't do the trick for my LO
We used bio gia and breaks during feeds and extra burping
