Welcome. Yes your daughter’s baptism is valid, since she is very young, it would simply be a matter of your going to your local Catholic parish, explaining that she was baptized in the G.O. Church, and that you intend to raise her Catholic. Your husband will need to affirm that he has no objections to her being raised Catholic. If he is or wishes to accompany you and your daughter at Mass, (without his receiving Communion) he is welcome, another option is becoming a member of a Byzantine Catholic parish. In that way you will be able to raise your daughter fully Catholic, but with the same liturgical rites that your husband is familar with. I’m not sure where you live, but in most major cities in the US and Canada there are Byzantine Catholic parishes that serve the needs of those who have been raised in the Eastern Traditions of the Church.
