My 1mo baby girl is drinking 100ml~110ml (fm) and she's vomiting quite a bit after feed/burp. Is that normal?

yes it's normal. Try burping her inbetween feeds to get some air out first before continuing feeding her

U can try to burp Inbetween feeds instead of finish the whole feed then burp

Burb her in between feeds rather then after a full feed.

Yes it's normal.
