If your child is struggling with certain sounds and words you may need to look into the possibility of tongue tie causing these issues although it is well known that there can be a number of causes for speech problems including: neurological problems, developmental delays, hearing difficulties, etc. Some of the speech problems that we have seen in tongue tied children are as follows:
Difficulty with sounds like L, T, D, N, SH, TH, R, or S once a child is past the age when these sounds are mastered
Delayed speech milestones
Lisps
Speech that sounds “slushy” or unclear
