My first one was actually really awesome - she was supportive of co-sleeping and a BF advocate and really didn't care much about parenting as long as we were happy so I saw her lots because I found the reassurance and support comforting. Since my Mum is dead and my MIL has subtle undermining down to an art form I kind of needed the IRL validation that I was doing ok.
With my second I had moved to a different area and there were a couple of nurses and they were all kinds of annoying so I only went once.
