I can highly recommend Annalou Low. She saw my son as a baby for weaning/swallowing issues and also a bit later on for speech (he had NG feeding tube, unsafe swallow, tracheostomy so it was quite challenging). She was really helpful in guiding me on weaning and has a really good manner with children. I was frankly amazed at how she got my 18 month to sit at a table and concentrate for his first speech session! She also helped a friend who had a very prem baby with serious feeding aversion/ swallowing issues and gave them a very clear strategy which really helped.
