I was raised CofE, went to church schools until 18 etc. I was then in a relationship where religion didn't feature and I drifted away, at an age where many do.
Many years down the line I started to get interested and attend church with a couple of friends who happened to be Catholic. I got into a new relationship, with someone born and raised Catholic but lapsed. I continued to attend the Catholic Church with my friend (cousin of then boyfriend now DH) I had 3 children all baptised Catholic, 2 at Catholic school.
This year I converted, there was no pressure to do so, I attend church regularly with DC, DH works weekends, could come more often than he does, but prefers a Sunday lie in.
I was asked if I was doing it to get the DC into Catholic schools, but I pointed out 2 already were and the same priest would be asked for secondary reference for DS and primary reference for DD2 in a couple of years and there were no changes since the references were previously given.
No, I was doing it for myself.
I would second the suggestion to speak to the parish sister, ours is fantastic, a real inspiration.
With regards to the contraception question, I wondered if I would be asked about my views on that, I wasn't. For me, I have been given medical orders not to have any more children. With DC2 I suffered a life threatening complication. With DC3 I had the same condition as previously, plus another separate one on top. I reconcile this by considering that I am doing the right thing by ensuring I am around to see my children grow up (the I obgyn consultant's words) and nurture them and their faith.
I know I'm not perfect, but I try to do the right thing.
