Got asked to be the God Mother of my Best Friends son! But...

So my best friend since high school, now has a 1 yr old son and just found out she's pregnant with her second baby. She told me before she told her husband 😂 anyways, I am so happy for her and can't wait to meet her little second minion. She asked me & my boyfriend to be the God parents of her first born (which I said yes too) but then I remembered I'm a Christian and I've never been baptized. I was wondering if I can still baptize her son?
