Have a look at this old thread... and hopefully someone with more recent experience can advise as well. xx
Ann Dobson is excellent. She'll come to your house and snip it there and then. She has assessed both of my babies (one snipped, one not!).
We used Carmelle Gentle and would recommend. She saw us at 5 days old and assessed and cut same day. Came out at very short notice.
Thanks all that's really helpful - I'll follow up
