I used to look forward to visiting my HVs as I had sleep problems with my first (he's now 20). I used to try putting their advice into practice (have the sleep diaries somewhere to prove it)! Got to remember that there was no internet links, mobiles, etc. and HVs (and Mums and Dads) were the only source of advice. With my second baby I did things slightly different but was lucky that she slept through the night from 6 months and also my third but they still had a dummy and teddy to go to sleep with which really helped settle them. I bottlefed all three and can remember sitting up with son with the bottle hanging out of his mouth in a perfect sleep and then putting him down and that was it, back to square one! Other than that my health visitors were great in giving me good advice about everything (not sure about the chips) and I think it's a good thing that they've made a comeback.
