My youngest son had tongue tie. Obviousy, not the most severe, but still enough to give him problems. He came into our family when he was eleven months old, having spent that time in a full-time nursery. I was told he had been difficult to feed, particularly in the earlier months when totally on bottles!!!
As a toddler in a large family, there was often 'competition' to see who could get their tongues onto their noses, but we all missed that he always lost these. Indeed, he was four years old, and making his usual mess trying to eat an ice-cream cornet when I finally saw the light about this.
Once I went to GP saying he had tongue-tie it was no time at all before he was referred to local hospital and the procedure took place one morning/ Just a 'smidgeon' of anaesthetic to keep him still, and he was back in my arms within less than a hour after that and home again that afternoon.
This was back in the late 1970's.
