I loved this story when you posted it on Team Dragon.
Reading it a second time, I love, love, LOVE Snape's entrance, but this line:
Sore nipples, sudden food aversions, an overproduction of saliva, and flatulence were several of the oddities that had developed of late.
I just plain ADORE!
Then there's:
Tucking the toy dragon under his arm, Harry trudged quietly up the stairs. Harry liked to have the plushie to remind him why what he was doing was important.
The toy dragon is a perfect addition to the household.
The foot rub still makes me drool!
Severus tipped Teddy's chin up with a finger. "Is there a reason for this caterwauling?"
Do they ever need a reason???
Quickly opening the pajamas, Severus was careful to keep the nappy on while he Summoned a clean one, having observed the child's propensity to shoot a stream of urine as soon as his genitals were exposed.
Ain't that the truth! Why are boys more 'liquid' than girls, I wonder?
I love the way you give each of them a child to hold and love, but I foresee sleep-deprived parents!
