My niece was 17, pregnant and unmarried too and her mother didn't think it was "proper" to give her a shower. Well.........don't tell me what right or wrong!! I gave her the biggest baby shower ever! I went all out with the decorations, gifts, balloons, etc. To this date she still thanks me for it.

Just because she is unmarried doesn't mean she should be treated any different than anyone else. Go for it, you will be happy and so will your daughter.

I just did a Internet search of "baby" and found a ton of information for showers, names, etc. You don't have to buy any books at the store or anything.
