DS2 has 1 but has been getting thinner as time goes on, when he first got teeth was a concern as he had a rather wide gap but seems to have improved over time.

Have had no BF issues and he is still BF at 2 and 1/2.

A friends son had 1 and she always had bad attachment and got pain, she made an appt to get it looked at and her son had a fall and spilt the frenulum himself.
