When did your loved ones feel the twins kick?

I'm 18 weeks pregnant with twins and I can feel them kicking me! It's becoming a really awesome feeling now that I'm beginning to tell the difference between gas and the babies!! I was wondering though, when will my loved ones be able to feel them kick? When was the first time your husband felt your belly and felt them kick? I'd like to hear from twin moms to better understand in a twin pregnancy.
