Heavy filter usage just makes it seem like you have something to hide.
Is it at least somewhat filled with good and/or interesting pictures? An organically grown Instagram account, showcasing your favorite pictures of yourself, holidays, friends, landscapes, whatever you find interesting, will lend some additional insight into your personality and complement your bio.
It also seems a lot more authentic than the portfolio of main pictures in your profile, handpicked (or even specifically taken) to be used for a dating profile.
Even if it’s your child and you want to filter out everyone who would not want to date a single parent, an online dating profile is just not the right place to share pictures of kids.
If you’re a social person (or would like to appear as one), having a few group shots in your profile is generally a good idea.
