Um - I actually think our HV is quite good. She came round to our house to do DS's 18 month check so he could be in his own surroundings. Gave us some useful discipline techniques less draconian than "Toddler Taming". She also told us she thinks the vaccination program is getting a little bit OTT and that she is refusing to give the new chickenpox vaccine when it comes in.
I know that HV's are restricted in what they can advise as they have to conform to government guidelines which isn't very useful. However she always seems really supportive and was great when DP stayed at home with DS and kept bringing list of parent and toddler groups where she had heard of other men going with their children.
Ha ha my granny works at baby clinic on the Isle of Wight and has done for 40 years. She weighed some of the HV's she now works with when they were babies!
