To receive communion one must be Catholic, have been prepared to receive communion (know what it is, why we do what we do, that kind of stuff), be in a state of grace (no mortal sin), and have observed the one hour fast.
So it sounds like your husband and kids (?) aren’t Catholic, so that cuts that out right there. The reason only Catholics may receive is because unlike many other Christians, in the Catholic church the bread and wine become the Body and Blood of Christ. Additionally, in receiving communion we are saying that we believe what the Church teaches and are in communion with the Church.
As for you, a baptized, but non-catechized Catholic, we are supposed to go through a period of preparation before we receive communion for the first time so that we know what we are doing when we receive, not so much physically (hold out hands, place host in mouth), but spiritually (receiving the Body and Blood of Christ).
As for where to go from here, the first step is to call your local parish and tell them that you were baptized Catholic but not catechized and your husband and children are not Catholic and would like to be (I assume that is what they want since you are asking) and they will help you go from there.
Generally, you will go through some classes to help you prepare for your first confession, first communion and confirmation. Often times this will happen through the RCIA (Rite of Christian Initiation for Adults) process, but your parish might have a separate group for those who are already Catholic. Your husband would also go through the RCIA process and prepare for which ever sacraments he needs (I’m unclear as to whether or not he has been baptized). As for the kids, it depends on if they are already baptized and how old they are. If they are under 7, you can have them baptized as infants and they will prepare for their first communion at the same time as their peers who have grown up Catholic. If they are older than 7, they will most likely go through a children’s version of RCIA and be baptized, confirmed and receive first communion at the same time. But like I said, the first step is to call your local parish and go from there.
And lastly, welcome back!
