We won't refer in neonates for anything but feeding issues; it's unethical and not financially viable to perform a procedure for potential speech problems etc.
That may be your view but it is not universally shared..
My DS was diagnosed with a severe TT by an observant paediatric registrar after five stricken days on the maternity unit being told by all and sundry that he was latched on and feeding well yet he lost 12% of his birth weight in 4 days and was clearly distressed and frustrated when feeding. Getting his tongue tie snipped made him into a different boy at a stroke and has also saved him a great deal of potential problems in terms of possible speech and dental problems. Unfortunately the delay in getting it diagnosed and treated meant that we were never able to establish bf. We had already had to introduce bottles to counteract the loss of weight and he was not up for re-introducing bf. Cue three months of exhaustion from expressing, and mastitis.
My older DD, on the other hand, was born prematurely and we spent 7 weeks on SCBU trying to get her to feed (bf and then ff) which led to a great deal of stress and upset. Even one we got her home (ff by that stage) she took ages to feed and would dribble most of each feed out. She was tiny anyway and it took ages for her to start gaining weight properly.
It was only when DS was diagnosed with TT that I realised that DD had had it too. The heart-shaped tongue which they both had, and which I thought was so cute in DD, was the giveaway.
It makes me quite angry that only one out of the many HCPs who dealt with DD and DS, only one was able to spot a TT.
In my opinion it is totally unethical not to treat a TT which is causing real problems to a baby both early on in terms of feeding problems and later potentially in terms of speech and dental problems. The collateral damage in terms of stress (and potential PND) to new mums struggling to feed TT babies should not be underestimated either.
With both of mine, TT was a fairly decisive factor in me having to give up bf which caused me a great deal of angst and guilt (not to mention the exhaustion of expressing to try to make sure my LOs got some bm). This was particularly hard for me to deal with as a mum with a baby in SCBU.
The procedure to snip TT, on the other hand, is very cheap and straightforward in newborns. I am at a loss to see why it is unethical in any way and it is certainly not an expensive procedure.
