“Bedtime snack,” Kim wrote.
Kim’s sister, and Mason’s mum, Kourtney gave birth to her second child a month ago and hinted this week she may be considering practising attachment parenting with her new baby daughter Penelope.
Kim appears to enjoy her role as aunty and recently revealed her own desire to start a family and her baby back-up plan (wonder what beau Kanye West thinks?).
Well, it certainly looks like Mason was enjoying himself in Kim’s care. Let’s just hope she helped him brush his teeth before bed!
