Baby stomach issues..

So my LO is 2 months tomorrow.

She's had tummy issues since day one.

However the doctor just keeps telling me it's normal baby problems, but myom thinks something's not right 🤷‍♀🤷‍♀

She will eat 4oz and spit up at least 2oz. Almost everytime.

She gets hiccups prolly 5-6 times a day.

Some days she won't poop.

She's super super gassy though.

Sometimes she will not take her bottle and cry and cry and chew on her hands like she's hungry.

Just wondering what all you other moms have experienced and maybe what I should so.

Side note she is formula fed on Simlac sensitive, and I cannot change formula because this is what WIC covers..
