I haven't used it but I bought the same one as Tamika. Bonjela said it was suitable from 6 months so I didn't buy it.
We use Ashton and Parsons too x
The Ashton sachets are very good. Plus Ambesol from 5 months
I have! It's the only thing that works for her, I started it early with my eldest too as it was the only thing besides calpol that worked for him too
I use the Ashton & parsons teething gel that’s 3 months plus x
