I can honestly say I think sure start saved my life.
I was referred by my HV, and a sure start staff member came to my house, got to know me and literally held my hand into a group, where I met loads of other parents from all walks of life. They then rang me a few times to see how I was, check I knew when groups were, see if I was having problems and so on.
When I went to the groups, there was always plenty of advice availiable in an informal way, a HV on hand, lots of good quality toys and educational materials. I can buy craft equipment for the children for cheap, I can borrow toys, there are courses on all aspects of parenting.
The whole thing with surestart is that everyone can go, they can mix. I know I would be very reluctant to go to a group just for mums with mental health issues, but I love going along and mixing with people from all different backgrounds, and knowing that support is there if I need it. People who are struggling can see good parenting modelled, instead of just being told aout it.
The "community" groups, while they are lovely, don't make any effort to include new people, and are basically a big room of plastic toys with no other facilities, and cost me, with two kids in tow, £5 entry. That is often too much. Also, the posher families seem to all go to the really expensive groups, so us poor mums get a bit ghettoised. At surestart everyone mixes.
And people who think breastfeeding support shouldn't be funded by the government can...well, read the statistics. Thats like saying smoking cessation shouldn't be funded. Madness.
