Hi, you'll have to trial and error all of the above you mentioned. Every baby is different. There are methods to help baby poo better, e.g. bicycle legs in the air, but as for what type of milk baby can take, there is no hard and fast rule.
Don’t apply ruyi oil. A lot of babies nowadays are allergy to it. Like my girl, we didn’t know. End up took a few months to recover from the bad rash from ruyi oil.
Hi... your baby is too young to self medicate. Please bring your child to see a pediatrician
