some babies spit out don't worry... keep the baby slightly upright position during feeding.. keep feedings calm and burp the baby after every feed...

Don't worry.  May be she take too much than required.  Make a habit to burp your baby always after or in between her feeds.  Hold her upright after every feeds.

Some babies have this habit of over feeding or puking .. If its not too much then dont worry .. Her weight gain should be ok

don't worry , try to feed in upright position i.e.keep her head little above her chest..and try to burp everytime after feed
