Second opinion about tongue tie

Hi mam and mothers

My son has the same problem… he is now 3+ .. he is absolutely fine in eating and speaking also .. touch wood … I was so worried for him and took him to doctors.. They suggested me to wait and watch his activities and speaking abilities. So when I noticed that he is doing well … I dropped the idea of surgery and all. Just want a suggestion, should I go for one more checkup? My last checkup was when he was 8 months old. I am very happy and thankful to God.
