When Harry entered the new room that would be his, which as next door to Ron's, Ginny's, and his new parents rooms, he was surprised. Everything was a nursery in here. As if he were still a baby. He had vague memories of a nursery's looks, based on what he could remember, when his "former" cousin had a nursery. But he never got to use one. All he got was a makeshift crib.
But the Weaslys wanted to show he was part of their family now, and he wasn't going to be treated any differently then his new siblings. There was everything here, from Diapers and pull-ups, to a child decorated television with movies for kids his age group, to a crib his size, or a bed should he want to lay there, or have one of the parents sleep with him, if he felt scared, to toys, both for what was considered to be for tots younger then him, and toys for his age group. And the floor, walls and furniture had been pushed up, so avoid causing him any injury, a luxury the Dursleys never provided. With magic, it was not trouble getting this together. And when other witches and wizards who knew Harry's parents, or at least of what had happened to him originally, donations came flooding in generously, even those who were across the Great Atlantic Ocean in the U.S. The Weaslys had gone from a Poor family to perhaps one of the richest families in the Wizarding World, Granted, some of the Wizards who considered themselves "purebloods" and "Nobles" did not contribute, due to their stuck up nature, but this bothered the Weasly's little, and they did not spend the money on meaningless things they all wanted that they'd probably toss out in a couple years time. They used it to repair the house, and now, it looked almost like a castle that would make the Royal Family of the Muggles Buckingham Palace envious. And the Weaslys agreed that much of this money would be used to keep all the children well looked after, and that meant Harry could get spoiled here.
And Harry's and Ron's and Ginny's rooms had been made bigger, thanks to all the money, so these nurserys could do well for sleep overs. After Harry was able to take in the surroundings of his new room, he asked, "Um..... Mommy, what are the rules of me being your son?"
Molly smiled, "Well Harry dear. Your just an adorable little tot, and I know that while the Muggles may have tried to hurry you into growing up, here, you don't have to try and act so grown up. I know I was trying to get my little Ron to get potty trained, but, I was being a little to speedy with that. If you wish to wear training pants or a diaper dear, just let me know, and I'll change you into one. And let me know if you need a change once you go. And if you're hungry, just let me know, and you can choose between drinking my mommy milk, like Ron and Ginny do, or you can have whatever we cook for meals dear, it's up to you, and your siblings won't give you grief for it. Do be aware though, when I say it's time for a nap or for bed, you do as mommy says. Oh, and if you want to play with Ron or sleep with him in his room, that's perfectly fine, since we let Ginny sleep with her big brother sometimes. They both may come to sleep with you in your room too."
This made Harry giggle a bit, knowing he wasn't the youngest in the family, but he also didn't have to act like a big grown up so quickly. He was also amazed Molly was willing to breastfeed him. Petunia spoiled Dudley with breastfeeding, but not him. He was given a bottle or real food, but now he had the choice of mothers milk. And he could choose what kind of padding he would want to wear, and his siblings wouldn't mind in the slightest, or tease him about it. He was then told what he could wear in public, but had the choice of going pantless at home, as Ron and Ginny often did, and he was given a run down of how things happened around the house, and when they went into town. It was all a lot more lenient then before the Weaslys adopted him. He was now Harry Potter Weasely.
After Harry asked for a diaper this time round, wanting the extra protection, now that he had the choice......
