Referring to your baby as little "ethnicity of parents"

Britania

I was messaging a friend of mine and she said "can't wait to meet your little filipinito lol" since my husband is from filipino descent. I found that rude because she's very sarcastic and says things with double meaning. Therefore my response was "He's a baby from Mexican and Filipino descent which is different." Did I take this too personal? Was it rude from her? Or was I overreacting? I just believe regardless of it's race or color it's a tiny living human not a little ..."".
