Baby dedication is not the same as infant baptism. It is a common practice among Baptists, Anabaptists, and Evangelicals for whom baptism is only an outward symbol of an inward change and reserved for those beyond an age of accountability.
However since you're going to a *reformed* baptist church I'm assuming that you're not going to just want to switch to a denomination that baptizes infants, but a Calvinist denomination that baptizes infants. This will take most of the infant baptizing denominations off the table as they (Orthodox, Lutheran, Catholic) are not Calvinists.
Given where you are currently attending, the following denominations would be a reasonable choice:
Presbyterian Church of America

Christian Reformed Church
Christian Reformed Church
If you're not philosophically in strong agreement with Calvinism and it isnt one of the reasons why you've specifically selected a reformed baptist church to attend, I'd choose one of these five all of which practice infant baptism:
Antiochian Orthodox Christian Archdiocese of North America
The Russian Orthodox Church Outside of Russia - Official Website
Orthodox Church in America
Lutheran Church - Missouri Synod - Locate A Church

Also, I'd say that perhaps its in poor form to turn this thread into a debate about infant baptism. We have a sister in Christ who expressed her preference for the practice and so we should simply answer the question to the best of our ability.
