I always go to the evening one as well. Its always the same nurses on too. I also trust them 100%. My kids have never made a big fuss about getting the needle & I think its because of the nurses technique. I had Glenn done once at the clinic during a day session & it was a different nurse, I didn't like her, it took a good 15 minuted to calm poor glenn down after his 4mth shots. The problem was she just jabbed him as soon as he was layed down, rather then letting him relax in the position, so he was all tense when she did it & I think that made it hurt more.
