"Bottles are in the fridge upstairs." she called to Harry, finding her own jeans and then summoning the rest of their clothes with her wand. It was likely that he knew as much already, but it was a situation where she would rather be safe than sorry.
Pausing to slip on the button-down shirt Harry had been wearing, Ginny headed up the stairs as well although she slipped into the bathroom to clean herself up, discard their clothes into the hamper that would banish them to the laundry downstairs. Then there was the matter of the milk James wasn't going to be eating because Harry was feeding him - Hermione had suggested the pump that she had been using, and it had been a life-saver. She remembered hearing her mum explain that she had literally been tied to The Burrow for years because nursing all of her children had meant she couldn't leave for more than a few hours. Naturally Ginny didn't want to leave James for days at a time, but having such a little device was invaluable.
By the time she had finished that task and taken the new milk to the fridge Harry was settled in, and James was happily sucking down a bottle when she walked back into their bedroom. And, as usual she had to grin at the sight, pressing a kiss against Harry's cheek before leaning over to peer at James. "You have Ron's appetite, I swear. Being small is not going to be a problem."
