I haven't personally but my brother in law and sister in law have judt had their little boys done, he was about 5/6 weeks old and was having issues latching to feed even with a shield he was struggling to get enough milk out. He's now almost 8 weeks old and is a milk monster 😅 Depending on the severity of the tie it can affect their feeding and then later on their speech as it restricts the movement of their tongue. It's a tiny little snip that will heal very quickly and is over before you and baby even know it!
If it’s causing feeding and latching issues then it’s 100% worth it in my opinion.
I had my LO done, he latched perfectly after, the only issue we had was it too so long to get it done that he would be frustrated as he couldn't get the milk out quick enough. However his cry changed and he loves sticking out his tounge now, I'm glad I got it down but he was 11 weeks
