Is it that, while drinking from his bottle, while staring up at you, he widens his lips, shows you his 5-teeth, whilst still gritting the teat between his teeth?
Is it that, afterwards, while suppressing your urge to laugh at His Royal Cuteness, that you grunt at him to get back to concentrate (as much as a 10 month old boy can muster) on drinking thru his teat, only to have him do the whole flash-my-5-teeth-at-you all over again?
Or is it that, occasionally while carrying him, he’d make a hmm sound, and then you make a hmm sound too, and then he makes a hmm sound back at you, and then you make a hmm sound, and then he makes a hmm sound too?
Or is it that, in the wee hours of the night, when you sneak into bed the most quietest you can be, and he wakes, and you grumble and swear under your breath and pat his back to get him to go back to sleep, only to see, in the littlest of available light, the little bugger is grinning back at you?
Or is it that, when a lady is carrying him, he would, index finger only, hook the top of the carrier’s blouse, tug-pull a little, and peer in to check out her boobs?
