My DD is 15mos old and has q. a severe tongue tie. Now she's my 3rd and all 3 have some degree of tongue tie. Also, I'm trying really hard not to seem over-anxious. DD can only make one sound which is 'ma'. All the others did 'da' first and were more verbal at her age.Even DS who didn't communicate (poss. ASD)said more at the sme age. Of course I'm being slightly neurotic as we are going through a process of diagnosing DS at the mo. I'm wondering if her tongue tie might be impeding speech, or being a 3rd child, or just maybe she'll babble and make more sounds when she's ready. She's v. active and has developed physically with walking well before I'd have expected her to.
