Does my newborn know I’m his mom?

Ok so this may sound stupid to ya’ll but I have this question... Does my newborn know I’m his mom? Like I’m on maternity leave right now and I spend so much time with him but I just have this side of me that worries he doesn’t know I’m his mom and won’t love me. Like I said I spend all day with him. I breastfeed, I do the diaper changing as well. My mom will pick him up and talk to him here and there and he will smile at her and that’s when I get this thought in my head of “what if he doesn’t know I’M his mom” idk it might be stupid to y’all...
