Posterior tongue tie - what to do?

I’m feeling uncertain and would really appreciate some guidance. My 2-month-old has been diagnosed with a mild posterior tongue tie. He’s primarily bottle-fed — both expressed breast milk and formula — with 1–2 direct breastfeeding sessions a day. Initially, he breastfed more, but he started getting fussy at the breast. I’m not sure if that’s due to nipple confusion or a latching issue. He had frequent hiccups in the womb and still gets them now. During feeds (breast or bottle), he makes clicking noises and tends to be gassy. He moves his tongue, but when he sticks it out, he also pushes his lip forward and doesn’t seem to extend the tongue over his lower lip. I also experience some nipple pain after he breastfeeds. Given all of this, I’m wondering if we should go ahead with a tongue tie release? Is it truly necessary or could it be an unnecessary procedure?
