I just recently purchased my daughter a new road bike. It came with 90 mm stem. She needs a much shorter one. Thinking about going with a 50 or 60.Will that work or could I have problems?

Impossible to answer with the information provided. There's nothing inherently wrong with a 50 or 60mm stem, but bike geometry and bike fit involves multiple inter-dependent dimensions, so much more information would be needed to guide a fit. I'd suggest taking her to a bike fitter.

Yes thanks. Just not sure if there would be any handling problems if I went with a shorter stem.

Go with the best stem length for her fit.

Going to an extremely short stem, especially something close to the MTB length, will certainly make handling a little more twitchy; it may not be a bad thing for the youth though, they can learn how to handle the bike properly.
Another way to go, depending on the handlebar already on it, is to find the shortest reach handlebar. I think Zipp has the SL70 that has only 70mm reach. You may be able to combine a short reach handlebar with a shorter, but not extreme short, stem to get where she needs to be, and not dramatically change the handling characteristics of the bike.

Hand position--and the effective lever--is all that matters, whether you get there with normal handlebars and a very short stem or a slightly longer stem and short reach handlebars cannot logically affect handling.

Thanks for all the help.

I should clarify--a shorter effective lever can absolutely affect handling. I was just stating that the length of the effective lever is what affects handling, what contribution the stem vs. the handlebars make to the effective lever is irrelevant, so for a given effective lever, there's no trick involved in shortening via handlebars instead of stem. It's worth pointing out that this also means that an incremental reduction in stem length is less significant than it seems, because the reduction's impact comes as a fraction of the length of the stem + the additional length offered by the handlebars.
