Hi I know them well: grew up in Bridgwater, worked alongside them briefly (used to work for HomeStart) and now sam attend, ahs done for almost 2 years.
We like their approach: its very family friendly, we can take the boys etc etc etc. Also JimJams is right to ane xtent but theya re evolving- for example the are trainings taff in new therapies (I think music? they were looking into it) and they ahev taken on quite a few staff, seem to ahve evolved immensely in the alst few years.
Funding- they haev a policy of never turninga way a child for funding. We found some for Sam, and they ahve a fund for anyone on benefits / low incomes.
The other option is the Brainwave centre, similar-ish (shared origins) approach. Wortha look, though not so hot on self publicity I do like them.
The thing about BIBIC is that everyone is entitled to a free interview (telephone) and lengthy discussion: that's worth a shot I reckon.
FWIW they have helped us immensely, both with therapies, practical stuff (they helped get the DX for Sam!), and theya re always there on the end of a phone if I need advice, whether behavioural or dietary.
If you go do let me know- that's for anyone on here- because I live near the Welsh unit and Mum lives right near the Bridgwater one, so could meet up.
Also FWIW I have known BIBIC as long as I can remember and would trust them with my son's life.
