She should put you in herself. Actually, "The Guide To Getting It On" suggests that all women should do this most of the time.

Absolutely. Before I gave birth I was a little small, and I used to find IC uncomfortable sometimes, especially when it had been a while (too long) between encounters, so it really helped for me to do the guiding. I still do it now, even though my size is no longer an issue.

BTW -- Mirena is an IUD with hormones that is inserted usually while the woman has her period, because the cervix is slightly open then. I tried the non-hormone IUD for a while. Insertion is very quick and just a little uncomfortable. She should take Ibuprophen an hour before her appointment to help reduce discomfort from cramping.
