I had heard a variation on this somewhere else--and chuckled at the time--but last night Natalia said it on her own.
Natalia: "Mommy, I'm really upset that you wouldn't snuggle me last night. I really wanted you and you hurt my feelings."
Me: "Honey, I can't cuddle you every night after we read stories. I needed to go spend time with Daddy."
Natalia: "You snuggled him and not me. It's not fair!"
Me: "Natalia, sometimes Daddy wants to be snuggled, too."
Natalia: [thinking about it] "Big baby."
