We went to one about 2 years ago and I think it went for almost an hour. Like you we had no idea what gift to get? I thought it best to stay away from religious items and I bought a really pretty picture frame. I would maybe ask the parents if you can and see what they prefer. If not then here are a few suggestions from what my DD got for her christening: jewellery, jewellery box, clothes, children's bible, books, money box, bookends, money.
