Hi C.,
Take a deep breath, everything is going to be fine. This is your life & your child. God is THE MOST IMPORTANT thing EVERYONE needs in their life. You go ahead & go to church & do your thing. Anyone who gives you grief about this, you either A. tell them "this is my decision & I really wish you'd respect it, and if you can't do that, then please mind your own business" OR B. don't socialize with those people anymore.
My husband is a Christian, as well as his family. My parents are Catholic & my brothers & I were baptised Episcopalian. LOL all I know is that I very strongly believe in God and in Jesus Christ & that my life has far more meaning with God & Jesus in it. My family had & still has nothing nice to say about this at all - and didn't even attend my own christian baptism. I came straight out to my parents & told them that they have no right to say anything to me about it. That I'd appreciate them to respect my decision & that if they can't then, well, we just wont' get together as often and/or we won't talk about it at all. - I'll tell you what, my family got over it quite quickly. We went through 2 weeks of no contact & finally my mom caved - and we agreed to just not talk about it, and that's ok.
But don't push God away, just because other people don't get it yet ok? God does the most miraculous things in people's lives - even the smallest ones make the biggest difference. And even when times get tough - he may be testing you, or it's just the way things are supposed to go for a little while, life is never perfect or 100% fun without any hard times. Keep your faith in God & trust him - he won't let you down - especially when you believe in Him with all of your heart.
God Bless & take care
