Is This How To Get A Child?

i was visiting my partners nephew today (he is 4) and we were playing with his toy cars. when randomly he stands up, grabs my hand and takes me to his mother who was in the other room reading a book. Mr 4 then walks over to his mum, tugs on her shirt sleeve, points at me and says "this is Mum" to which his mum responds "no. thats auntie Jo. im Mum." Mr 4 smiles before happily exclaiming "No. Thats Mum." i then say "no. thats mum." and then he smiles really big. points at both myself and his mum and says "Two Mums!" before hugging his mum and then hugging me. i swear my heart melted so fast. im so happy to have this little man to ground me during my ttc struggle.
