Present situation- Reed and North sitting at North's little table, eating a post-nap snack.
Reed: "Look North, Mommy's belly is getting big. Your little brother is growing inside her."
North looks at Reed, then continues with his snack.
A few minutes later, as the two are playing with toys, North goes up to Reed and pokes Reed's belly.
North: "Baby?"
Background info:
Reed has a bit of a belly and is currently very motivated to decrease the girth. I have joked that it is his turn to nurse this time around as it decreased my body fat very easily when I first started nursing North.
I think this little hint from his child might increase his motivation even further!
