I've had experience with 5 different HV and they were all incapable idiots.
3 times they failed to turn up to the scheduled appointment. When I called they acted surprised and said the HV was sick and apologised nobody called to let me know. I find this hard to believe with 3 different HV?!
In my LA the HV do the hearing screening during a home visit. I was assured it was glitchy technology and that failed tests happens all the time. The HV proceeded to say that my boy can 'obviously hear' due to his responses.... he's profoundly Deaf. I was also given books and encouraged to read to my son and use baby language.... the HV couldn't even remember he is deaf during the appointment let alone in any subsequent appointments.
I was told my boy was underweight on 2 occasions. The HV then went on to say how breastfeeding perhaps wasn't the best option as I couldn't be sure how much milk he was actually getting..... he was exclusively breastfed, gaining weight and meeting all milestones. Ridiculous guidance from a young HV.
Finally, at our 10 month review, I was sent a big load of paperwork tick box things to fill out in preparation for a phone appointment. I waited for the call but it didn't come (yep, staff sickness again!). When they called the following week (unexpectedly), I went with the flow and continued with the appointment, retrieving the paperwork I had completed in advance. The HV was very concerned by his lack of verbal communication (despite him signing 10+ words on his own!) and told me I should stop relying on sign language and use more spoken language to encourage him to talk... WTF?!
At that point, I submitted a complaint and insisted I be withdrawn from any future services offered by the HV team. They were each a bunch on incapable, embarrassingly prejudice, subjective plonkers.
I have no doubt there are some brilliant HV out there but alas, I didn't meet them.
