You don't say how old you are or what level of playing you have achieved in 7 months, but here are some principles:
First of all, most student players do not double on piccolo. Even in professional and semi-professional groups, only one flute player is designated as the piccolo player for every song that has piccolo. In other words, this role is not passed around to give other players a turn to try it. Piccolo is a very similar, but also different instrument than flute. It needs careful approach to play it well.
Piccolo is also not a stand-alone instrument. When you upgrade in flute, you get a better flute. You don't turn in your flute for a piccolo. A piccolos is an instrument that a flute player might own in addition to other flutes.
Before even considering trying to play piccolo, you need to ensure that you have amazing air support and breath control while playing your flute. You need to be able to consistently play every single note on your flute in tune. Be disciplined and use a tuner to check. Control over your embouchure goes along with this so that you can do all kinds of articulations without going out of tune.
The piccolo is notorious for being difficult to play in tune due to its size. It is also notorious for being extremely shrill. Flute players with a strong embouchure and a good sense of intonation and tone will be able to control the piccolo and make it sound good. Some flute players may have an easier time of this depending on the shape of their lips and mouth. Piccolo is not for every flute player, even great flute players.
