You could actually do a lot with the children's voices already ingame used by children before you can adopt them or their parents die and just cut and reuse that when you actually adopt them (such as Sofie saying "I'm so cold", or Braith's dialogue for wanting to fight and have her very hostile to any other children) and use them for certain locations you have them living in. Also the kids in the orphanage that you put there all only say the same thing and lose their indiviuallity. Adding some of their previous dialogue would be cool and say still have Britte chasing Sissel, but now inside the Orphanage (in mine Aeta is glitched and says she must get back to her village which I like as it her saying something different from the rest) As for the orphanage when Grelod is in charge the children should do work such as brushing the floors all day, also perhaps have one kid locked in "the room" randomly with a lock on the door that only Grelod has the key for, and then maybe playing more in the garden when throughout the day when Grelod is dead and having some play with toys. I would love to have actual different clothes for the children so they look different with some clothes looking very dull and raged like for the orphans, and better off kids such as Lars Battleborn wearing very fancy wealthy clothes. I also hate how in the unmodded game how when your children leave the house that they do not interact with the other children at all (unless play tag), In solitude they walk to the front gates of the city walking past and completely ignoring the 3 local children. I would like for them to talk to local kids (reusing whatever dialogue is already ingame). In Whiterun my daughter always claims to get bullied by Braith or plays with Lucia yet I Never see her interact with either, and sons always claim that the Dragonreach is "so cool, but the kids there are mean". Why not have them visit it once a day and have the noble kid's say their mean dialogue towards them. There is also a mod that changes the childrens looks which I have seen so add this to this mods and it would be awesome. This face-changing mod makes the children look less like identical potato heads and makes some of them the correct race such as Braith who becomes a Redguard. Another idea, howabout when the children ask for money depending on how much you give them the house and their clothing changes so if you give them loads the house will be full of food and children wearing nice clothes, and if you give them little or no money the house will run low or out of food and the child will wear more ragged clothes. Also you could use Lucia's "I'm so hungry" dialogue if she never gets any money. Also the children's pets could be improved such as have the child lie down and play with the pet at least rather than them always ignoring it and it simply following them and never sitting or lying down (such as when the child is in bed and the pet just stands looking at them the entire time). Boys also can't be given dolls so why not make them a toy soldier or allow them to use the children's doll. Furthermore when I make the children do chores or give them a doll they always go and stand at the exact same posistions to do them, why not give them more, and add more interactions between kids such as two of them sitting or lying facing each other interacting such as playing with their dolls with each other or fighting each other with wooden swords (which you could interact and tell them to stop it). You could also give girls baskets like the one Sofie has when she is living on the streets and have them go outside and look like they are picking flowers (I think there is dialogue where girls say they will pick flowers). How about adding action where when fighting a child may swing her/his arms in a punching or pushing way. I really hope someone makes some of these ideas into a mod as I'm quite surprise no one has improved kids at all yet (bar the changed heads mod). Here's a link to it http://skyrim.nexusmods.com/mods/38712//? Another idea Samuel states that he sneaks out of the orphanage when Grelod is working in her room so why not have this happen ingame where if you watch him he will leave the orphanage and go around Riften trying to pickpocket of the locals (then runaway if spotted and hide in an alley).
