Christening our kids

Heather
What are your thoughts on Christening your children? My oldest is 3 and youngest is 8 months. Is it too late? I was baptised Catholic and my husband Lutheran. We do not actively go to church although both believe in God and after life. My 3yo is enrolled in a Baptist preschool so she will be exposed to some religion next year which I am happy about bc I do think it is important for her to learn.
