Hi, I need some help regarding my 10-week-old daughter. She has a tongue tie. Its heart shaped when she cries, it can't extend beyond her lips , it looks like the tip of the tongue is attached  to the lower gum. She feeds for a very long time (40-60 mins), gets tired, and falls asleep I should keep stimulating her. Her weight gain is within normal limits but on the lower side ( birth weight - 2.9kg , weight at 9 weeks 4 days - 4.5kg). Does she need frenotomy? Is frenotomy done on kids of her age?Does tongue tie cause feeding issues & problems while eating solids? She does not have any problem latching but feeds for a very long time. She feeds every 2.5 - 3 hours in day. Night every 4-5 hours . Does not cry & is not fussy either. Thanks in advance.
