My son is 17 weeks

Growing normally weighing about 18lbs now?

But he spits up all day long...he’s not in pain when he spits up...he doesn’t even react to it. But it’s all day long about an ounce at a time.

He sleeps through the night and I haven’t noticed any spit up in his crib so I don’t believe it’s happening during his sleep.

Lately he’s been very fussy and about 2 times a day he cries out in pain! I think it’s his tummy bothering him he curls into a ball and screams in pain.

He’s been having normal bowl movements

I’m thinking this could be a milk protein allergy?

I was thinking of switching him to a hypoallergenic formula?

We don’t go to the doctor until the 28th.

Any advice????
