It’s not cheating, is it?

I’m at my in-laws, and I feel like I’m having to look over my shoulder when I am playing with my 9 m.o. niece. Because if my 21 m.o. (only child) daughter catches me, she gets really upset that I am “cheating” on her with another baby. 😬🤷🏼‍♂️😅 via /r/Parenting http://bit.ly/2LzV3vg
