my LO is EBF since birth and now she's 8 weeks i tried giving her formula since i am about to start working but after few hours she cried and her skin become cold, when i hold her she started throwing up, immediately she closed her eyes which really scared me.
was the formula could be the main reason for her stomach upset?
The formula could be the reason for her upset tummy. But it could also be something else, like a virus. There's no way to tell for sure without trying the formula again at a later date, and seeing if the reaction is the same.
I suggest consult your doctor.
Your baby may be ill, I have no idea what would make her skin turn cold. Certainly formula violently disagrees with some babies, it is also possible baby ate too much with the bottle, a common issue.
And I agree with mommal. Why does baby need formula, will you not be able to pump or hand express at work?
