How do you say I love you mommy and daddy?
I love you mommy and daddy
¡Los quiero mucho, Mami y Papi!
¡ Los Adoro mucho, Mami y Papi!
That's how I'd say it, but again like ChamacoMalo said, it's all up to style of speech.
I would have said Te amo mamacita y papacito.
Yo les amo los dos, papito y mamita. That's how I'd say it, but other have their own style of speech, and will share their way of saying it.
Los quiero mamita y papito or, los amo mamacita y papasito.
