Honey, I know it is so so easy to worry about them not getting enough, or if your milk is enough for them. Especially as we can't see how much they are getting! If only boobies were seethrough and with markings for how many oz they were eating
Seriously though, what you're describing is VERY normal and actually what a newborn nursing pattern looks like.
She eats every 2-2.5 hrs (although sometimes she seems hungry even after only 1.5 hrs). During the first wk she seemed to go longer between feedings but now she eats more often.
They also go through many growth spurts during the first weeks, so that's why she'll sometimes want feeding really frequent for a few days, to then start going longer again (up to 3 hrs maximum for most babies at this age)

About your diet... I really don't think you need to worry about it. It is very unlikely that your diet would affect your milk supply especially at this early stage. I'll post you a link to a list with lots of links about mom's diet while BF. Hopefully this will help you feel less worried
